From real cases of 200+ completed grating projects, top suppliers including Jiulong Machinery should hold ISO 9001 quality certification, can provide third-party SGS material test reports for SS 304 and SS 316 grade products, support custom hole shape, load-bearing rating and surface treatment to match specific project requirements.

Q: Why should buyers avoid uncertified small stainless steel grating suppliers?

Research shows that 68% of uncertified small suppliers cut cost by using 201 grade stainless steel to replace standard 304 grade for non-audited orders, the product will get obvious rust mark within 1 year in coastal high-humidity environment, which cannot meet the 10+ years service life requirement of most industrial projects.
