Key Features
- Superior Anti-Slip Performance: Features specially designed serrated bearing bars or anti-slip plate surfaces that provide outstanding traction, ensuring safe passage even in wet, oily, or icy conditions.
- Integrated Safety Design: Can be customized with integrated nosing strips, warning strips, or kick plates to form a complete fall protection system, complying with the most stringent safety regulations.
- Excellent Drainage & Ventilation: The open mesh structure ensures water, snow, dirt, and debris do not accumulate on the tread surface, keeping stairs clean and dry while reducing cleaning and maintenance costs.
- High Strength & Lightweight: Significantly lighter than solid steel plate treads (up to 50%-70% weight reduction), lowering the load on the stair support structure and easing transportation and installation.
- Flexible & Quick Installation: Offers various installation options including bolted, welded, or clip-on systems, allowing for easy adaptation to diverse stair structures and on-site conditions.
Frequently Asked Questions
1. What is steel grating?
Steel grating is a framework of metal bars, where parallel bearing bars are joined to perpendicular cross bars (usually by welding or locking) to create a load-bearing panel with an open grid pattern.
2. What are the common materials used for steel grating?
The most common materials are Carbon Steel (ASTM A36), Stainless Steel (304 or 316), and Aluminum (6061-T6). Carbon steel is typically galvanized for corrosion resistance.
3. What is the difference between "Bearing Bars" and "Cross Bars"?
- Bearing Bars: The vertical bars that carry the main load.
- Cross Bars: The connecting bars extending perpendicular to the bearing bars, used to provide lateral stability.
4. How do I determine the span of a steel grating?
The span is the distance between the points of support, measured parallel to the bearing bars. Even if the width is greater than the length, the direction of the bearing bars always defines the span.
5. What are the different types of surface treatments?
- Hot-Dip Galvanizing: Most popular for rust prevention.
- Powder Coating: For aesthetic or color-coding purposes.
- Pickling/Passivation: Used for stainless steel to remove surface contaminants.
- Mill Finish: Raw steel without any treatment.
