dovetail pressure locked grating Introduction:

Steel Bar Grating, also known as Welded Steel Bar Grate is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle traffic. Steel Bar Grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements. Available in either smooth top or serrated for slip resistance.

• Specifications: 19W4, Carbon Steel, Painted Black

• Applications: Walkways, flooring, ramps, bridge flooring, trench and drainage covers, mezzanines, platforms, stair treads, etc.

• Workability: Easy to Weld, Cut, Form and Machine

• Mechanical Properties: Tensile = 58,000 +/-, Yield = 42,000 +/-

• How is it Measured? bar thickness X bar height, Bearing bars run parallel to each other, the length of the panel.

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
