Application

1.Walkways
Provides a safe walking surface in factories, warehouses, and industrial facilities. The slip resistant open grid design enables debris, liquids or dirt to fall through.

2.Steel Staircases
Suitable for industrial and commercial stair treads when strength and slip resistance are required. Serrated or non slip inserts are available on request for adding further safety.

3.Work Platforms
Accommodates people, machines, and tools in work shops or repair bays. Ventilation andshine-easy open pattern of design.

4.Drainage Areas
Open grating allows water, oils, and other fluids to pass through. Often used in factory floors, outdoors and running alongside drains channels.

Our Advantages

It is made of ASTM A1011 carbon steel which has good load-bearing capacity and long service life.

Customizable Design
Size, mesh size, bearing bar spacing and surface interest can be customized to meet the requirements of the project.

Corrosion-Proof & Weather-Resistant
Optional hot-dip galvanizing, powder coating, or painting for indoor, outdoor, or marine use.

Safe & Non-Slip
Drainage, ventilation and slip resistance for safer workplaces Open-grid promotes these 3 essential health and safety factors.

Applications
It is widely uses for walks, platforms stairs treads work areas and drainage systems in industrial and commercial applications.

Quality ISO 9001
Designed and manufactured from high grade material with ISO 9001 certified standards for trusted output.
