What is Steel Bar Grating?

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.
Grating Manufacturing Methods
1. 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.

2. 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.

3. 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.

4. Welded Swaged Pressure Locked

It is an upgraded version of the swaged pressure locked. Each intersection is manually welded once to make it stronger and can withstand more loads.

Applications

Steel gratings are known for their high strength and durability, and play a role in many fields:

  • Used for bridge guardrails and drainage ditch covers in municipal engineering
  • Used as factory platforms and petrochemical plant equipment supports in industrial facilities
  • Suitable for stair treads and light wells in architectural decoration

It is also widely used in industrial platforms, stair treads and other scenes to meet the needs of load-bearing, anti-slip, drainage, etc., and is both functional and economical.

Steel grating applications in industrial settings
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.
Frequently Asked Questions
What are bearing bars and cross bars?
Bearing bars carry the load; cross bars hold the bearing bars in place.
Can steel grating support heavy machinery?
Yes, with proper design, steel grating can support industrial equipment.
How is steel grating installed?
It can be mounted on support frames, welded, bolted, or anchored depending on the structure.
Can steel grating be cut on-site?
Yes, using cutting tools suitable for steel, such as angle grinders or plasma cutters.
What is the difference between welded and pressed steel grating?
Welded grating has bearing and cross bars welded; pressed grating uses pressure-locked joints.
Is maintenance required for steel grating?
Minimal maintenance is needed; periodic cleaning and inspection are recommended.
