What are your guidelines for assembling with glass clamps?
To create a barrier infill, toughened glass is a versatile material. It is strong, cost effective and readily available. The size and thickness of each glass piece is governed by various factors:
The spacing of the posts:
For public locations that demand a 0.74kN/m handrail, our Standard posts are spaced at 1460mm maximum. For this, the glass will be 1365mm long. Local Building Control will advise further on barrier specification.
Where this is (usually) 1100mm, the glass will be 870mm high. If the handrail is at 900mm, the glass will be 670mm high. Local Building Control will advise further on appropriate handrail heights.
Strength or duty:
This varies according to building use category. 10mm toughened glass is adequate for the duty described above.
This can be achieved with the blade post ATSSPO5 and 12mm glass
Our glass clamps are lined with nitrile rubber. Various thicknesses of glass can be accommodated and some have a security plate or pin to prevent slippage of heavy pieces of glass. We recommend that the glass clamps are attached to the posts. The posts have the wall thickness and strength required and no bottom rail is required to frame the glass. To assist with the installation of these items, we can supply drawings, technical help and a limited choice of tools and fasteners.
All the fittings require the use of Loctite 638 or similar retaining fluid. Fasteners are provided where necessary.
How do I maintain stainless steel products?
Andy Thornton 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).
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. Separate data sheets on this topic are available.
The installer must appreciate the potential problems caused by surface contamination. Mild steel particles from tools, cutting discs or even hands, will impregnate the surface and will rust. In anticipation of this, the experienced installer will ensure that his tools are clean before commencement and will clean and passivate the surface after assembly. Passivation is the application of dilute nitric acid which restores the vital inert layer to the metal surface. Proprietary solutions are available for this purpose.
In the case of immersion or spray of sea water or swimming pool water, where the following maintenance cannot be carried out, please seek further advice from us.
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.
Prevent the accumulation of dirt. A regular wash with warm water and mild detergent (such as car shampoo) followed by a clean water rinse is sufficient. Done diligently, this is all the maintenance required.
If dirt and staining has become established, then a mild non-scratching abrasive powder such as a household cleaner (not bleach or chlorine based) can be used. Apply with bristle brush and wash off with lots of clean water. Fingerprints and grease marks can be removed with glass cleaner or washing soda. Again, rinse thoroughly. The proprietary “E-Cloth” is recommended to restore an unmarked appearance to stainless steel.
If rust appears, do not worry, this not a disaster. Airborne contaminants may include free iron which will settle on the stainless steel and oxidize. This is common on or near building sites or any construction activity. Special cleaners are available that will remove the rust and leave a protective film on the surface. Andy Thornton Ltd can supply such a cleaner. Ask for details of Cleaner C.
Small scratches and stubborn stains can be removed with 3M Scotch-Brite or similar nonmetallic scouring pads rubbed “along the grain” DO NOT use steel wool or Brillo pads which leave particles that will rust.
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.
