5mm Crossbar Welded Steel Grating For Construction ASTM A1011

5mm Cross Bar Square Shape Chemical plant ASTM A1011 Standard Welded Steel Grating

Welded Steel Grating Introduction:

Galvanized Steel Grating, Removable

Galvanized steel grating plates:

Steel plates welded on certain flat steel bar and spacing with the high-pressure welding machine welded together is called steel gratings. The cutting, incision, opening, the package-processing procedures are necessary as customer demand for the finished product. Its characteristics include high-intensity and light structure. The grid is a firmly welded steel bar structure with a high capacity, light structure, easy loading and other characteristics like aesthetic appearance. The hot-dip zinc surface treatment gives it a good anti-corrosion capacity, shiny surface appearance and durability for uses. It is suitable for places and sites requiring ventilation, explosion proof, lighting resistance, heat resistance materials. Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, well covers, ladders, fences, rails, and so on.

Steel Grating is made by stainless or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. Industrial bar gratings can be actually made from copper, aluminum and other materials, while galvanized steel grating is the mostly used one due to its economic cost and good property.

Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.

Materials:

Mild carbon steel provides an economical, high strength for uses in most industrial and commercial applications.

The advantages, specific application and features of steel grating:

Steel grating offers the following advantages compared with steel grid sheets:

Steel grating has light weight, good strength, large carrying capacity and can save materials and cost. It offers good ventilation of light and wind, a modern sense, aesthetic appearance and anti-skid safety. It is also easy to clean, easy to installation and durable for uses.

Steel grating products are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering, and they offer the following the features:

Aesthetic outlook: Simple lines and silver appearance meeting the modern trend.

The best drainage: Leakage area of 83.3 percent, more than twice of cast iron products.

Hot-dip galvanized treatment: Good rust-proof property, maintenance-free replacement.

Anti-theft design: The cover and the frame is joint with hinge offering security, safety and open convenience.

Savings investments: Large-span. Less lost for heavy load compared with cast iron products. Cost can be saved for the risk of being stolen or crushing one if cast iron is uses.

High strength: The strength and the toughness are much higher than cast iron. Can be used for terminals, airport and other large-span and heavy loading condition.

Specifications: More specifications and sizes optional for meeting various environment, load, span, sizes and shapes.

Surface Treatment:

Steel grating untreated: Allowing quicker delivery to customers whom fabricate and galvanize the grating on their own.

Galvanized: Hot Dip Galvanizing can give a hygienic and clean maintenance free bright finish.

Stainless Steel Grating

Stainless steel bar grating is a choice for corrosive environments such as chemical, food and hydro processing areas. It is available in welded and press locked as well as in many bearing bar sizes.

Materials: The most common material is Type 304 (SUS304), however, Type 316 (SUS316) or Type 316L (SUS316L) is also available. 304 stainless steel is the most popular type contains both chromium and nickel to provide excellent balance resistance and workability. 316 stainless steel is better corrosion, pitting resistance and higher strength at elevated temperatures than 304. 316L is extra low carbon variation of 316 to avoid carbide precipitation due to welding.

Aluminum Grating

aluminum grating is designed to be a high-strength, low-weight product that uses an I-bar or rectangular bearing bar with cross rods hydraulically swaged under high pressure. Thus, giving you a rigid, virtually maintenance-free flooring product.

Similar to steel grating, aluminum grating can be pressure locked as an alternative to swage locked. This application process also allows the customer to choose a close mesh grate where certain special needs are to be met.

Open Mesh Grating

The open mesh steel grating is a flat panel with a light structure firmly welded together. It is widely used for industrial ladders, decking safety, ventilation ceilings and floors, platform and stair tread protection panels. The open spacing design instead of solid metals allows good ventilation, and easy flow of lighting and heat. The standard sheet size is 1m x 6m standard type (special size and American standard size are also customizable).

Mostly Used Specifications of Steel Mesh Gratings from our customers:

1) Bearing Bar (Load Bar) Specifications (mm): The specification of plain type and serrated type bearing bar is 20 x 3 to 100 x 10; The specification of I-section type is 25 x 5 x 3, 32 x 5 x 3, 38 x 5 x 3, 40 x 5 x 3, 50 x 5 x 3, 50 x 7 x 4, 55 x 7 x 4, 60 x 7 x 4, 65 x 7 x 4 , 70 x 7 x 4, 75 x 7 x 4, etc.

2) Bearing Bar Pitch (center to center): 12.5, 15, 25, 30, 30.16, 32.5, 34, 40, 41.25, 45, 50, 60, 60.32, 80, 100 mm etc, also be according to client's requirement and 30, 40, 60mm are recommended, America standard is available.

3) Material: Mild Steel (Low Carbon Steel) or Stainless Steel

4) Surface Treatment: Mill finish untreated, Painting or Hot DIP Galvanizing

Mesh gratings are popular due to the following features:

1. High strength and light structure

2. Powerful anti-corrosion, durable and long working life

3. Beautiful appearance, bright surface

4. No dirt-rain-snow deposit, automatic cleaning, easy maintenance

5. Good ventilation, day-lighting, heat-dispersing, resistant to sliding and explosion.

6. Easy installation and disassembly
