We stock stainless steel tube and components in grade AISI 304 and grade AISI 316.
Grade 304 is standard grade and is suitable for all indoor and the majority of outdoor locations, but its use is not recommended near swimming pools or within 0.5km of static sea or within 5km of surf. The surface finish is fine brush or 340-400 grit (≤0.5μm Ra). This is a practical, scratch disguising finish, which is not damaged by the cleaning process.
Grade 316 is marine grade which is suitable for all locations, given the correct maintenance. The finish is 340-400 grit (≤0.5μm Ra).
Installation must be carried out by an experienced installer. Unless a specific request has been agreed, the parts we supply are not pre-assembled. Basic metalworking tools and techniques will be necessary, such as for cutting, drilling, tapping and filing.
A cleaning schedule is essential, not only to maintain appearance, but more importantly to preserve corrosion resistance; stainless steel needs to be clean to self-renew its special surface properties.
The fine finish of stainless steel can always be recovered. If neglect has caused discoloration (known as 'tea staining') or even corrosion and pitting, the surface can be restored by re-polishing and passivating as above.
