Environmentally friendly high-tensile steel grating.

It is listed as a general item for price reference (high-tensile steel grating) and can be widely used in both public and private construction projects. The main material uses high-tensile steel, which has higher strength than conventional steel, achieving an average cost reduction of 2% compared to SS400 steel grating of the same standard, as well as a reduction in weight and approximately 25% less CO2 emissions during manufacturing and transportation. It is available in a wide range of specifications, including coarse and fine mesh, cross-sectional and longitudinal, with load capacities from T-2 to T-25.
