Product Description
Heavy Duty 19W4 Aluminum, Galvanized Steel, Stainless Steel, Catwalk Deck Floor Steel Bar Grating Drain Trench Cover Price for Walkway Platform
Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.
Main Components of Metal Bar Grating
| Component | Description |
|---|---|
| Span | Total span |
| Width | Panel width |
| Bearing Bars | Load carrying the main element |
| Bearing Bars Spacing | Measure from center-to-center of the bearing bars in 1/16″ increments. Standard spacing for industrial flooring is 19/16″(1-3/16″) in the center. Other popular spacings are 15/16″, 11/16″, 1/2″, and 7/16″ on center. |
| Bearing Bars Depth | Ranges from 3/4″ to 7″ depending on anticipated loads |
| Bearing Bars Thickness | Ranges from 1/8″ to 1/2″ depending on anticipated loads |
| Cross Bars | Used to Secure the position of bearing bars |
| Cross Bar Spacing | Measured from center-to-center of cross bars in 1″ increments. Standard spacing is 4″ or 2″ on center. |
Welded Grating
The most commonly used and economical design suitable for most industrial applications. Manufactured by welding the bearing bar and cross bar intersection, typically with automated forge welding equipment or professional manual welding. Available in carbon steel or stainless steel.
Dovetail Pressure Locked
Insert the cross bar into the pre-punched bearing bar and hydraulically deform it to lock it in place. The cross bar here is usually a straight plate shaped like a bearing bar.
Swaged Pressure Locked
Assembled by inserting pre-punched bearing and cross bars into an "egg-crate" configuration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental applications.
Surface Treatment
We provide four finishes for anti-corrosion treatment of carbon steel bar grating:
- Black / Bare Steel: No finish, life is very short, but the price is the cheapest.
- Painted Coat: The anti-rust effect is general and can be any color.
- Electro-galvanized: A small amount of zinc coating, easy to cause slight corrosion in humid environment.
- Hot-dip galvanized: The most commonly used method to provide the best anti-rust effect, strictly in accordance with ASTM A123 or GB/T 13912-2002.
