Application
1. Pedestrian passage
The human-shaped passage formed by steel grating provides a stable and slip-resistant walking surface for the workers in the factory buildings, workshops and storage areas.
2. Steel staircase
A suitable staircase tread for industrial and commercial scenarios, balancing load-bearing strength and anti-slip requirements.
Optional toothed anti-slip models or anti-slip inserts can be selected to further enhance safety.
3. Work platform
It is widely adopted within workshop and service zones to hold machinery, tooling and operating personnel. The open layout improves air circulation and simplifies surface cleanup.
4. Drainage area
The open grid construction enables water, oil and other fluids to drain freely. It finds frequent use on outdoor grounds, factory flooring and alongside drainage channels.
Our Advantages
1. Anti-slip and safety performance
The perforated grille itself has anti-slip, drainage and ventilation effects, enhancing the safety level of the working area.
2. Wide application scenarios
Suitable for various projects in industry, commerce, infrastructure, etc., can be used in passageways, platforms, stairs, work areas and drainage positions.
3. ISO9001 quality certification
Produced strictly in accordance with high standards, with stable and reliable performance and good quality consistency.
4. Quick delivery, comprehensive support services
Flexible production, packaging and shipping plans, delivery time 7–15 days, with an experienced customer service team.
