  2. 2. Manufacturers and Installers of: Flooring Steelway Fensecure has displayed for Heavy Duty Gratings over eighty years the expertise for design, manufacture and installation of Walkways our specialised equipment. Staircases We offer our customers the assurance of equipment complying with relevant Platforms British Standards, Code of Practice and Building Regulations backed up ladders by quality assurance control in our works. architects, engineers and others Duct Covers now have the benefit of our experience brought together in this Catalogue Ball Type Handrail Systems of products engineered by Steelway Fensecure. Guidance will readilyFlush Welded Handrail Systems be given by our Engineers for the architectural Balustrades specification and type of Steelway Fensecure equipment most suitable for your project. This help is available from the outset when the initial plans Screens are being drawn up. It will prove invaluable to the architect, Engineer and Draughtsman alike. access Covers Steelway Fensecure are frequently asked, not only to manufacture and Component Fabrication supply equipment, but also to assemble and erect installations on site. Experienced teams of Steelway erectors undertake this work, controlled in Mild Steel from the Wolverhampton works, they operate in all parts of the u.K. mainland. Stainless Steel In the interest of quality and customer service, we pursue a policy of aluminium continuous product development and reserve the right to modify product designs without notice. Due to the limitations of space we have not been & GRP able to illustrate our complete product range.

  8. 8. Mild Steel & Stainless Steel Floor Plate Durbar raised pattern non-slip mild steel solid floor plate. This plate may be used for trench covers, platforms, stair landings and stair treads. The raised leaf pattern, having no enclosures, provides increased non-slip surface to give firm grip in all directions. For particularly slippery conditions a carborundum surface finish is available. Plates of this type are self draining and readily cleaned, therefore minimising corrosion and ensuring longer life. Trench covers, which are to be readily removed, are holed for and supplied complete with standard lifting keys. Where necessary, plates are cut to clear pipework or other obstructions and are countersunk drilled for securing to steelwork with fixing screws. PGP HEAVY PATTERN Mild Steel Floor Plate is available in 4.5, 6.0, 8.0,10.0 and 12.5mm base thickness. Primer Painted or Galvanised. In Stainless Steel available in grades 304L or 316L. Aluminium Tread Plate Aluminium tread plate, designed primarily for flooring applications provides a non-slip, easy clean, hard wearing surface, which has found extensive use in Industrial, Marine and Transport fields. Tread plate comes in three popular patterns to suit various conditions of service and personal preferences. Thickness for thickness, in a particular material, the load bearing characteristics of the three patterns, are not significantly different, but a choice does accommodate factors such as pedestrian comfort, durability, and aesthetic consideration. Applications vary from kick plates to loading ramps, from factory flooring and stairtreads to protective facias. Supplied self-colour.

  12. 12. Companion Step or Ship Type Ladders This type of ladder provides an improved means of access over the normal single run ladder when space is available. The 65 degree to 75 degree slope is easier to negotiate than a vertical or near vertical ladder. We recommend that the maximum vertical rise should not exceed 3000mm and the width between stringers should preferably be between limits of 450mm and 550mm. It should be noted that 250mm minimum foot space should be allowed from the nose of treads to the wall, platform face or other obstruction, see illustration. A top tread should be provided at floor level, or the platform can be arranged to run over, but the minimum foot space should still be maintained. Handrails are necessary on this type of ladder and should be provided on both sides without exception. Chart giving useful recommendations for staircases This chart gives preferred rise/go dimensions see section coloured yellow for any given rake of staircase or ladder and is based on our recommended formula: Twice the rise plus the go = not less than 570mm nor more than 640mm (550 to 700). ‘Go’ is the term used for the horizontal dimension of a stair or tread. ‘Rise’ is the vertical dimension. ‘Overlap’ is the amount the nosing of one tread overlaps the one below (minimum16mm). Example: A single flight stair has a rise of 2600mm and has to comply with a minimum tread ‘go’ of 250mm and a maximum rise of 190mm. From the chart below we see with a ‘go’ of 250mm an acceptable rise will be about 185mm. This will give 14 equal rises. The stair will thus have an angle of rake pitch of 36º 36’ and will fall within the limits required for this type of stair. Also the aggregate of twice the rise plus the go equals 620mm, close to the optimum recommended in BS 5395 Part 1.10
