Frequently Asked Questions
What is a stainless steel post base cover used for?
It covers the post mounting plate, bolts, welds and installation marks, giving the railing base a cleaner and more professional appearance. It is a decorative cover rather than the primary load-bearing flange.
Can the center hole and cover diameter be customized?
Yes. VVINSCO can customize the center hole, outside diameter, height, material grade and surface finish according to a drawing, sample or confirmed specification.
Should buyers choose AISI 304 or AISI 316?
AISI 304 is suitable for most general railing projects. AISI 316 is recommended for coastal, swimming pool, marine and other chloride-exposed environments.
How should stainless steel base covers be cleaned?
Use clean water, mild detergent and a soft cloth. Rinse and dry the surface after cleaning. Avoid steel wool, strong acids and abrasive tools that may damage the polished or brushed finish.
