Engineering Capabilities, Serge Ferrari Membranes, and Steel Metallurgy
At Archway Tensile, our interdisciplinary engineering wing comprises structural engineers, tensile architecture modelers, metallurgists, and certified site supervisors. Every project begins with rigorous analytical modelling using specialized membrane analysis software to simulate pretension, wind pressure (per IS 875 Part 3), thermal expansion, and seismic resilience (per IS 1893).
Membrane Material Spectrum & Serge Ferrari Portfolio

Structural Mild Steel (MS) & Stainless Steel (SS) Engineering
Fabric membranes depend entirely on an unyielding boundary perimeter. We engineer structural skeletal frames using high-tensile hollow structural sections (YST 210, YST 310 grade round, rectangular, and square hollow steel pipes per IS 1161 and IS 4923). All pipe bending is performed via CNC cold-mandrel induction bending to maintain uniform cross-sectional geometry without wall thinning or crimping. Fabricated joints are welded using submerged arc or gas metal arc welding (MIG/TIG), ultrasonically tested, shot-blasted to SA 2.5 profile standards, hot-dip galvanized or coated with epoxy zinc phosphate primers followed by high-solid aliphatic polyurethane (PU) finish coats. Perimeter hardware, turnbuckles, cable clamps, and tensioning swages utilize AISI 304 and marine-grade AISI 316 stainless steel to ensure zero corrosion under sustained tensioning.
Core Architectural Tensile Forms and Engineering Metrics
Tensile fabric structures obtain stability exclusively through double-curved anticlastic (saddle/hyperbolic) or synclastic (dome/catenary) geometries under uniform pre-stress.
1. Conical Tensile Structure

Manufacturing, Fabrication, and Quality Assurance Standards
At Archway Tensile, quality control starts with mill test certificates for every steel batch and continues through automated membrane preparation:
CNC High-Frequency (HF) Welding: Serge Ferrari composite membranes are pattern-cut using automated CNC cutting plotters to within millimetre precision. Seams are fused using high-frequency dielectric welders, creating molecular weld joints stronger than the parent fabric itself.
Pipe Bending and Structural Finishing: Structural round and hollow sections are cut via laser profiling and bent using continuous hydraulic roll-bending machinery. Frameworks are sandblasted, anti-rust zinc-primed, and sealed with automotive-grade two-pack polyurethane paint systems to withstand 1500+ hours of salt-spray testing.
Pretensioning and Site Erection: Membranes are rigged utilizing calibrated load-monitoring hydraulic jacks and stainless-steel rigging screws. Correct pre-stress prevents dynamic wind flutter, avoids ponding water retention, and guarantees structural performance throughout seasonal monsoons and high-velocity wind events.
