Features:

High strength, light weight. Their firm pressure welding grid structure contributes a lot to their high performances like high loading bearing, light srtucture, easy for installation, good appearance, long service time, etc.

Application:

Widely used as platforms, walkways, trestles, drain covers, well covers stairs, fencings, guardrails, etc.for petrochemical industry, power plants,water plants, sewage treatment plants, municipal engineering, environmental sanitation engeneering, etc.
