Each DDA tread is pressed from S275 mild steel with a raised anti-slip durbar pattern, a 265mm going, a 50mm turn-up at the rear and an extended 145mm turn-down front nosing. The deep nosing gives a pronounced visual and tactile step edge that supports compliance with accessibility (DDA \/ Equality Act \/ Approved Document M) design principles for public buildings.\u003c\/p\u003e\n\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cp\u003eMaterial grade: S275 mild steel — minimum yield strength 275 N\/mm²\u003c\/p\u003e\n\u003cp\u003ePattern: Pattern 1 raised durbar anti-slip checker plate\u003c\/p\u003e\n\u003cp\u003eGoing (width): 265mm\u003c\/p\u003e\n\u003cp\u003eNosing: 50mm turn up (rear) \/ 145mm turn down (front)\u003c\/p\u003e\n\u003cp\u003eLengths available: 1000 and 1250mm\u003c\/p\u003e\n\u003cp\u003eThickness: 4.5mm\u003c\/p\u003e\n\u003cp\u003eFinish: mill finish (self-colour) — ideal for painting a contrasting nosing colour\u003c\/p\u003e\n\n\u003ch2\u003eCommon Uses\u003c\/h2\u003e\n\u003cp\u003eDDA durbar treads are specified for accessible staircases in schools, hospitals, retail units, offices, leisure centres and other public buildings where a clear step edge improves safety for visually impaired and less able users. The extended 145mm down-stand is typically finished in a contrasting colour or anti-slip nosing strip to highlight each step, while the raised durbar pattern provides slip resistance across the full tread.\u003c\/p\u003e\n\n\u003ch2\u003eFitting \u0026amp; Workability\u003c\/h2\u003e\n\u003cp\u003eEach DDA tread is supplied with its pressed nosing ready to bolt or weld to a steel or timber stringer. The self-colour finish is ideal for priming and painting, allowing the deep front nosing to be finished in a contrasting safety colour. S275 durbar plate can be drilled, cut and welded with standard steelwork methods and galvanised after fabrication where external corrosion protection is required.\u003c\/p\u003e\n\n\u003ch2\u003eDDA vs Standard Durbar Treads\u003c\/h2\u003e\n\u003cp\u003eStandard durbar treads use a short 40–50mm nosing suited to industrial stairs. DDA treads add an extended 145mm front down-stand to create the pronounced, high-visibility step edge needed in accessible public environments.
