Modular 40mm Square – 5800mm – SHS 40mm x 40mm TUBE – SS316L SATIN (1.5mm wall thickness) NOTE: All stainless steel products require ongoing cleaning maintenance. To assist with cleaning upkeep it is recommended to use a proven stainless steel treatment, particularly where a Satin finish is selected. EnduroShield Stainless Steel Protective Coating aids in the minimisation of ‘tea stain’ issues occurring on the stainless steel surface. ** Satin finish railing is recommended for indoor installations only. For external railing, consider high polish finish to minimise tea stain possibility.
