Architectural
Staircases.

MS (Mild Steel) staircases are more economical and are finished with powder coating, PU paint, or hot-dip galvanizing. They work well for internal residential stairs, industrial access, and external staircases where the finish is painted. SS (Stainless Steel — 304 or 316 grade) staircases have a natural corrosion-resistant finish, require no painting, and suit premium interiors, coastal environments, and food/pharma facilities. SS 304 handles most indoor and sheltered outdoor applications; SS 316 is specified for marine or chemical exposure. Cost difference is roughly 2.5-3x for SS over MS.

For a comfortable residential staircase, we typically work with a riser height of 150-175mm, tread depth of 250-300mm, and minimum clear width of 900mm (1000mm preferred). Headroom clearance must be minimum 2100mm throughout. Landing length equals at least the staircase width. These comply with NBC 2016 guidelines. For duplex apartments with space constraints, we can design tighter geometries down to 750mm width and 200mm risers, though comfort reduces. All dimensions are confirmed in shop drawings before fabrication.

A standard residential staircase (straight flight or L-shaped) takes 3-4 weeks total: 2-3 days for site measurement and drawing, 3-4 days for drawing approval and revisions, 12-15 days for fabrication, and 1-2 days for installation. Complex designs (helical, curved, cantilevered treads) add 1-2 weeks for fabrication. External fire escape staircases with galvanizing add 4-5 days for the HDG process. We provide a project-specific timeline in the quotation.

Yes — this is how most of our premium residential and commercial projects work. The architect provides concept drawings or 3D renders, and we engineer the structure to achieve that design. We handle the translation from aesthetic intent to fabrication reality — stringer profiles, connection details, material selection, glass fixing methods, concealed fasteners. We share shop drawings with the architect for approval before fabrication. If a design detail is structurally impractical, we propose alternatives that preserve the visual intent.

Residential staircases are designed for minimum 3 kN/m2 live load per IS 875 Part 2. Commercial and public staircases are designed for 5 kN/m2. Industrial access staircases handle higher loads based on specific requirements. Additionally, railings are designed for a horizontal point load of 0.75 kN at the top rail per IS 875. All load calculations are documented and can be certified by a structural engineer if required by local authorities.

We fabricate four main railing types: (1) Glass balustrade with SS top rail — 12mm toughened glass panels in SS shoe channels or standoff fittings, (2) SS pipe/tube railing — 38mm or 50mm diameter SS 304 pipes with horizontal or vertical infill bars, (3) MS flat bar railing — flat bars welded in geometric patterns, powder coated, (4) MS pipe railing with glass — combination systems. Glass panels are always 12mm toughened safety glass. All railings meet the 1050mm minimum height requirement for residential and 1100mm for commercial.
