Ant Access supply a tubular handrail system manufactured from grade 316 materials. This is a versatile system which can be used in aggressive / corrosive environments. A range of finishes means this system can also be used for feature handrails.
All parts are totally pre- fabricated before delivery in accordance with bespoke drawings prepared for every individual contract . Each piece of handrail is marked to facilitate identification, this in conjunction with the drawings provided, ensure quick trouble free assembly.
Generally handrails should be not less than two rails in the same plane, however on companion way ladders and on stairs bounded by a wall a single handrail should be fitted. Handrails should be continuous and to avoid injury or damage, rails should terminate in a returned end. All joints are concealed within the ball via an internal groove type ferrule.
Resistance to loads imposed by the handrails and fixings should be considered when designing the structure that the handrails are intended to be attached to.
Handrail standard sizing will vary according to the shank type require for the determined loading / specification. This will affect in turn the ball diameter needed.
Base plates will normally be welded on to the shanks and drilled to received M12/M16 bolts as required. Larger / thicker bases may be required to those shown for heavier duty loading.
Where handrails are provided for attaching to customers equipment or to building structures, adequate consideration must be given to the design of such structures to resist any loads imposed by the handrails and fixings.
Finishes:
- Self Colour (untreated) Stainless Steel Handrails
- Pickled and passivated Stainless Steel Handrails
- Brushed Stainless Steel Handrails
- Matt Stainless Steel Handrails
- Electro-polished Stainless Steel Handrails, (following pickle/passivation)
Loadings should be a defined in BS6180:1995, BS EN ISO14122: 2001, BS5395 Part 3:1985 & BS6399 Part 1:1984.
HANDRAIL STANDARD / SPACING GUIDE
Tubular and solid standards.
Spacings of handrail posts will be determined by the design loading required. Handrails are normally 1100mm high with handrail standards typically pitched at 1500mm, (sizes of standards and rail will vary according to the loading). Where handrails are required above 1100mm spacings may reduce accordingly.
Handrail standards can be supplied with flat or side palm bases for connection to either steelwork or concrete.
Direct contact with some metals such as Copper or Aluminium, should be avoided. Use of suitable isolation materials will alleviate any problems.
