Stainless Steel Direct has introduced a new line of 316L stainless steel tubing. All tubing is sourced in North America from quality US and Canadian manufacturers with ISO 9001:2000 Certification. The marine grade tubing’s ultra smooth finish prevents environmental contaminants from sticking to the metal’s surface. The 316L stainless steel is selected for outdoor, marine and industrial uses where anti-corrosive properties are a must.
