Components are fully compatible with each other across finishes and component types - you can mix mirror posts with satin clamps if you want a feature contrast, or specify a single finish throughout. Glass clamps, joiners, brackets and end caps are sized to 42.4mm or 48.3mm round tube - check your tube diameter before ordering fittings.\u003c\/p\u003e\u003ch2\u003eBulk \u0026amp; Trade Orders\u003c\/h2\u003e\u003cp\u003eFor trade orders, full balustrade specifications or multi-component fit-outs (balconies, staircases, swimming pool surrounds), contact us for a project quote - trade pricing is available on volume orders.

Both diameters share the same range of compatible fittings (posts, clamps, brackets) - just stay consistent within a single install.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long are the standard tube lengths?\u003c\/strong\u003e\u003cbr\u003eStandard round tube lengths are 1m, 1.2m, 1.5m, 3m, 5.8m and 6m. The 1m-1.5m short lengths are for stair handrails and short wall-mounted runs. The 3m length is the standard 'work length' for most balustrade jobs - easy to handle and ship. The 5.8m and 6m lengths are for long uninterrupted runs (corridors, balconies) and reduce the number of inline joiners required. Rectangular and oval glass-channel handrail is available in 3m and 6m.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's the difference between 316 and 304 stainless steel?\u003c\/strong\u003e\u003cbr\u003e316 stainless contains molybdenum which gives it superior corrosion resistance against chlorides (salt, swimming pool water, marine air, de-icing salts). 304 stainless is the standard interior-grade - cheaper, perfectly fine for dry indoor use, but will eventually pit and stain in coastal or pool environments. For external use, marine applications, swimming pools, balconies and any salt-exposed location - always specify 316. For indoor stairs, dry environments and budget projects, 304 is the right choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSatin or mirror finish - what's the difference?\u003c\/strong\u003e\u003cbr\u003eBoth 316 satin and 316 mirror are the same grade of marine stainless steel - the difference is the surface finish only. Satin is a brushed\/lined finish that hides fingerprints, scratches and water spotting - it's the standard architectural choice. Mirror is a high-polish reflective finish - more decorative, premium-looking, but shows every fingerprint, water mark and scratch. Pick mirror for showcase installs (luxury homes, hotels, retail), satin for everyday commercial and residential use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's the delivery lead time?\u003c\/strong\u003e\u003cbr\u003eLead times are 3-5 working days for stainless steel handrail components to mainland UK addresses.
