Profile Section

195x88x1.5mm S235JR Uncoated Steel Sigma Plus Profile

The 195x88x1.5mm steel Sigma Plus profile is a cold roll-formed Σ+ section to EN 10162 with a deep stiffened 195 mm web, 88 mm flanges, fixed 25+15 mm double lips and 1.5 mm sheet thickness, weighing a nominal 5.64 kg/m. Produced to order in uncoated S235JR steel, the Sigma+ indent and double lips raise buckling resistance for heavy purlins, columns and long-span structures. This variant is uncoated cold-rolled structural strip in grade S235JR (EN 10025), minimum yield about 235 MPa. The surface is bare — specify shop painting or hot-dip galvanizing in the quote when the profile will be used outdoors.

Applications & Usage

Sigma+ 195x88x1.5 is the weight-optimized choice for heavy purlins, columns and long-span rafters where a standard Sigma or C is not enough. The deep web indent and double lips allow thinner material for the same performance, cutting steel cost and foundation loads on industrial and agricultural buildings. S235JR is the general structural grade for indoor frames, painted purlins, and profiles that will be hot-dip galvanized after roll forming. At a nominal 5.64 kg/m and cut-to-length production from 1 to 15 m, material usage is optimized with no offcuts on site. Minimum production run is approximately 3000 kg per size and grade — add your sizes to a quote request and our team confirms exact tonnage, lead time and delivered pricing.

Indicative elastic section properties computed from the nominal centerline (thin-walled, corner radii ignored). For preliminary sizing only — not a substitute for a stamped structural calculation.

Indicative load span (single span, simply supported)

Allowable uniformly-distributed load (kN/m) limited by elastic bending about the strong axis (γ = 1.5 on yield, S235JR). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
