Binze's composite steel grating utilizes a load-bearing steel grating as the base, with a sealed checkered steel plate or steel mesh bonded to the surface via welding or press-locking. The base plate provides structural strength and permeability, while the top plate ensures anti-slip, sealing, and fall-prevention functions-effectively addressing the drawbacks of standard steel grating, such as large apertures that allow small objects to fall through. We offer customization of base plate specifications and top plate thicknesses to meet specific operational requirements, balancing load-bearing capacity with anti-slip performance.

Product Features
Integrated Load-bearing & Anti-slip
The base grating provides structural strength, while the surface checkered plate enhances anti-slip and sealing properties.
01
Fall & Debris Prevention
The sealed surface effectively prevents small tools or materials from falling through and keeps the grating surface clean.
02
High Structural Rigidity
The base and top plates are securely welded or press-locked, ensuring uniform load distribution and resistance to deformation over long-term use.
03
Upgradable Anti-slip Performance
Options include serrated base plates combined with checkered plates for superior traction in wet or oily environments.
04
Corrosion Resistance
Standard hot-dip galvanized finish makes it suitable for outdoor and humid industrial environments.

FAQ
Q: What are the main differences between composite steel grating and standard steel grating?
A: Composite steel grating features a chequer plate or steel mesh attached to the surface of a standard steel grating base, creating a sealed surface. This effectively prevents small objects from falling through while enhancing slip resistance, making it suitable for grain silos, cafeterias, precision workshops, and other areas requiring sealing and fall prevention.
Q: How does the slip resistance of serrated base plates compare to that of flat base plates?
A: The base plate, made of serrated flat steel, features 0.5–1.0 mm serrations; when combined with a patterned top plate, its slip resistance is over 40% higher than that of flat-surfaced alternatives. It is suitable for wet, oily, rainy, or snowy environments, such as offshore platforms, slaughterhouses, and mineral processing plants.
Q: Can the surface be made of stainless steel?
A: Yes. Both the base plate and the top plate can be made of 304 or 316 stainless steel, making them suitable for applications requiring high corrosion resistance and hygiene standards, such as food processing, pharmaceuticals, and chemical manufacturing.
