The Ultimate Guide to Choosing Pvc Coated Gabion Box

Whether you&#;re looking for an erosion control solution at your project or want to use them as an architectural element inside or outside a building, gabions have a lot to offer. They not only prevent soil erosion on coast lines but are also great at preventing landslides and washouts. You can use different types of gabion baskets to provide stream-bank stabilization or reinforce roadside slope erosion problems. You can also use them in constructing decorative and sound dampening fences for residential and commercial applications as well as use larger baskets for security and fire protection in a variety of applications including government and military.
Gabions easily blend with the local environment due to the ability to use locally sourced fill material. Because they can drain water easily, they are highly stable as a retaining structure. Because of the easy availability of a wide variety of aggregate as infill, designers rely on them for high quality urban and landscape architecture elements. By designing and constructing gabion baskets properly, they can meet both structural and architectural design criteria associated with a retaining wall.
But for the most effective use of gabions, you must select the right type of materials for constructing your gabions depending on the area of application and project-specific requirements. The most common materials include galvanized steel, stainless steel, raw steel, PVC coated steel, and copolymer plastic.
Below are different types of gabions and their specific applications in different environments:

Galvanized Steel Gabions
These gabions are constructed of either welded steel wire mesh or double twisted wire mesh that is hot dipped galvanized. Galvanized gabions show excellent results for protection against general exposure and are the most common type. Galvanized protection on gabion wires from zinc has proven to be an excellent general purpose option with its inherent corrosion resistance. They tend to have a useful life of around 25 years on average. However, the actual design life depends on many factors including water exposure, salinity and acidity of the soils and run-off, as well as environmental pollution.

PVC Coated Galvanized Steel Gabions
PVC coated gabions can be either welded wire mesh or double twisted woven mesh gabions. In both cases the steel core wires are fuse bonded with PVC coating after hot-dip galvanizing and applying primer. They make solid and rigid structures by providing excellent protection in extreme environments. The PVC coating layer provides added protection for use in environments where soil or water is acidic or polluted. The protective coating prevents the risk of corrosion and is ideal for retaining and erosion applications in freshwater.  

Stainless Steel Gabions
Without the need for any extra process, stainless steel gabions have great natural features and are available in both 304 and 316L Stainless Steel. Aesthetically, stainless steel gabions easily incorporate with architectural designs and are available in a range of wire diameters and mesh sizes depending on the aesthetic preference and the material that will be used as fill. They&#;re fire-resistant and don&#;t require extensive care. They are resistant to corrosion or rust throughout the wire instead of just having a coating on the exterior of the wire. For applications around the ocean or highly corrosive soil, marine-grade stainless steel gabion materials can greatly improve the project life but it should be mentioned all steel when exposed to saltwater for extended periods of time will eventually rust.  

Polypropylene Plastic Gabions
In contrast to conventional steel wire gabions, these UV-stabilized polypropylene gabions are a more affordable option that gives you long-term durability while allowing for flexibility in rough or uneven areas. PP marine gabions are non-reactive for the marine environment and are treated to maintain UV resistance. PP marine gabions are ideal for bodies of water where wave energy dissipation is needed to reinforce the shoreline. They also help in scour-protection and maintaining the integrity of structures close to the shoreline.  

Raw Steel Gabions
 If you are looking for an original rustic look for your project, raw steel gabions are cheap and readily available. While the patina they develop is very attractive due to the lack of coating on the steel the life span can be greatly dimenished depending on the severity of the environmental conditions. That is why these gabions are generally used in arid conditions or in applications where they are not exposed to large amounts of moisture. You can apply powder coating or a clear coat to increase the lifespan but this would require additional onsite maintenance.

Hot dipped galvanized wires are used in a variety of ways. This article describes the features and specifications of hot dipped galvanized steel wire, its applications, and answers from frequently asked questions about the subject.

Features of Hot Dipped Galvanized Wire

Hot dipped galvanized steel wire is available in two types, namely mild steel and stainless steel. The mild steel hot dip galvanized wires are further divided into three kinds. They are the plain hot dipped galvanized wires (electrical armored), structural hot dipped galvanized (mechanical) armor wires, and non-armored hot dipped galvanized steel wire.

The stainless steel wires are divided into two types, namely bright annealed and hot dipped galvanized. The former is used to make food-grade products only. In contrast, the latter is applicable for automotive applications, pressure vessels, pipelines, etc., requiring high tensile strength and corrosion resistance.

Features of hot dipped galvanized wires include:

• Corrosion resistance (hot dipped for longer service life)
• High yield strength (provides high tensile strength and load-bearing capacity)
• Low cost (cost-effective when compared to other materials in the market)
• Lightweight (reduces total cost of the material because lightweight steel wires need less support, transportation means, etc.)
• Low fatigue failure (resists metal fatigue during long-term use)
• Easy installation (hot-dip galvanized steel wire is lightweight, which makes it easier to handle)

Hot Dip Galvanizing

Rapid deterioration of non-galvanized steel components such as iron poles, lamp posts, and signposts is a widely known drawback. Damaged steel is easily corroded by atmospheric conditions such as humidity, rainfall, etc. It speeds up the rusting process and leads to unsightly metal structures and increased replacement costs.

An alternative solution is a hot dip galvanizing applied on steel components that are to be exposed in outdoor conditions. The process involves immersing the base metal (usually mild steel) under an electrolytic charge of zinc ions in a molten bath of molten salt at elevated temperature (at least 30 degrees Celsius).

The hot dip galvanizing process provides better protection against atmospheric corrosion than other paints, powders, and cold-applied zinc methods.

Hot Dipped Galvanized Wire

• Used in fencing (strands for woven wire fences)
• For reinforced concrete (reinforced with steel mesh-like weave)
• Chain link fences (hot dip galvanized wires are less expensive than wrought iron or steel fences)
• Power transmission structures (applied for high load-bearing capacity applications)
• Architectural structures (applied for ornamental purposes)
• Aviation industry (for aircraft support systems, cabling, etc.)
• Hydropower industry (used for underwater power cables, hydraulic tubes, etc.)
• Landscape art (applied for metal railings, sculptures, etc.)
• Telecommunication industry (for towers, masts, signages, etc.)
• General construction uses

Other Uses of Hot Dip Galvanized Steel Wire

Metal buildings are made from hot dip galvanized steel wire. This is because the process provides resistance against corrosion and rusting. Hot dip galvanized steel wires are also used for other buildings such as gazebos, pavilions, and garden furniture where the frame needs to be strong and corrosion-resistant.

FAQs

What is the difference between galvanized and hot dipped galvanized?

A: Galvanization, or galvanizing, is a process where a zinc alloy coating is applied to an iron base metal. It serves to protect the surface of the metal from rusting, although if enough force is applied, it will still scratch or be punctured. Galvanized wire is a very thin wire coated and does not have any electrical insulation properties.

Hot Dipped Galvanized Wire is giving another layer of zinc alloy coating for galvanizing the iron base metal that has already been produced from the galvanizing process. The additional layer protects against corrosion and wears along with the strength and insulation of the wire.

How long will hot dip galvanize last?

A: Hot-dip galvanizing is a permanent process. It cannot be repaired or scraped off like paint and other types of protection finishes, and it must be done again if another layer of zinc alloy coating is desired.

What are the disadvantages of Galvanising?

A: There are several, as it is a chemical process that uses the hazardous metal cadmium. It is also more expensive than applying other finishes such as paint and powder coating and does not produce as aesthetically pleasing results.

What is the process of hot dip galvanizing?

A: First, the iron base metal is cleaned by removing oil and grease with a solvent. The base metal will then be dipped in a molten zinc bath at a temperature of approximately 450°F. It must be shaken off periodically during this process to ensure that it is evenly coated. Afterward, the wire or other product will be dipped in a bath of hot water and then transferred to a cooling tank of air or oil, which is where it will be quenched.

Does galvanized steel need to be painted?

A: The zinc alloy coating does not produce any insulation properties, so if electrical purposes are necessary, the wire should be insulated after hot dip galvanizing.

Can hot dipped galvanized steel be painted?

A: Yes, as long as the coating of zinc has not been damaged too badly. It should be sandblasted and primed with silicon-based paint before applying any topcoats such as enamel or powder coating. Like other surfaces painted, the galvanized surface should be cleaned with a solvent before painting.

Sunshine Fencing supply professional and honest service.

Can hot dipped galvanized wire steel be powder coated?

A: Yes, after cleaning and sandblasting, it can be treated the same way as any other metal that will receive this finishing treatment. It will probably need to be primed if it has been only hot-dip galvanized before applying a topcoat.

Can steel be hot dip galvanized?

A: Yes, steel can be galvanized with the same process as other metals such as iron and aluminum. The zinc alloy coating will not stick to stainless steel, so this metal type must have another coating applied before hot-dipping galvanizing.

Why is hot dipped galvanized wire more expensive than regular galvanized wire?

Hot-dip galvanizing is an operation that forms a strong and corrosion-resistant zinc coating on steel or iron. This process is applied to sheet or coil stock, as opposed to just applying paint.

Regular galvanizing is just coating steel with zinc. Any regular galvanized paint is just that &#; regular paint, not galvanizing.

Galvanizing coatings are designed to protect against corrosion. There are two kinds of galvanized coatings: electroplated and hot-dip. The primary distinguishing feature between the two types is their origin; one originates from electrolysis, and the other originates from molten metal.

Electroplated galvanizing is just coating steel with zinc and does not protect as well as hot-dip galvanizing. Zinc is a cathodic protection element; it is sacrificial, which means it corrodes first before the base metal (steel). If there is no zinc coating on the steel, then the steel will rust first. 

This galvanizing can be done by painting a base coat of paint onto the steel. It is just a temporary coating that eventually flakes off due to contact with moisture and other corrosives.

If there is going to be a coating over the electrolytic zinc coating, then hot-dip galvanizing is the preferred coating method because it forms a strong bond between the steel and zinc.

With hot-dip galvanizing, steel will not rust &#; it will remain in its current condition (will not rust) unless there is damage to the zinc coating itself where moisture can reach the steel.

Can hot dipped galvanized wire rust?

A: If the zinc coating is intact, then it will not rust. The only way the zinc coating would fail is if there are cracks or holes in the coating or if the steel underneath is exposed due to damage to the coating.

If hot-dip galvanized steel rusts, is it more or less resistant to corrosion?

A: If the zinc coating is intact, then it will provide excellent protection against corrosion. There are no free ions of metal with an intact coating that would allow galvanic corrosion to occur. This means that hot-dip galvanized steel would be more resistant to corrosion than bare steel.

What happens if hot dipped galvanized steel rusts?

A: When zinc corrodes, it will form an insulating barrier that prevents further corrosion of the underlying material (steels). Steel rusts through a process called electrolytic oxidation; this is the same process that is used in hot-dip galvanizing.

Remember that if there&#;s bare steel, it will oxidize no matter what you do to it except hot-dip galvanize it or paint it. If there are holes in the coating, though, moisture can get under the coating due to rust damage and cause more rust.

Is it better to paint hot dipped galvanized wire or leave it as is?

A: The choice of painting should be based on whether there will be a need to modify the surface, either by mechanical means (grinding, drilling, etc.) or chemical means (paint stripper). If a mechanical modification is needed, the painting should be avoided, making the surface rough. This would make the process of mechanical modification more difficult to accomplish.

If chemical means are necessary, then paint must first be removed before hot-dip galvanizing. 

If there are any paints or other coatings on the steel, those must be removed before applying hot-dip galvanizing. This can be done by sandblasting or some other method depending on the application and the coatings present.
