Application Scenarios
Steel grating consists of bearing bars and cross bars joined by automatic press welding machines. Widely used in petroleum chemical industry, power plants, water and sewage treatment plants, municipal engineering, and environmental sanitation engineering fields for platforms, footpaths, ditch covers, manhole covers, ladders, fences, and guardrails.
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.
