Pre-Engineered Building Systems & Advanced Thermal Cladding
Full architectural analysis, metallurgical yield tolerances, structural fabrication parameters, and PIR/PUF thermal envelope integration engineered by Krypson Infra Private Limited per IS 800:2007 & MBMA standards.
PEB Engineering Anatomy & Material Matrix
Explore the 5 core layers of Krypson Infra high-tensile structural frames, secondary cold-rolled load carriers, and polyurethane core envelopes.
Primary Built-Up Portal Frames
High-Tensile ASTM A572 / IS 2062 Gr. E350Custom-fabricated tapered columns and rafter flanges joined via automatic submerged arc welding (SAW). Yield strength 350 MPa with high seismic fatigue resistance.
Secondary Framing (Z & C Purlins)
Cold-Formed Galvanized Steel (275 GSM)Precision cold-formed Z & C purlins, eave struts, sag rods, and angle bracings with factory pre-punched staggered holes for quick on-site bolting without hot work.
Continuous Injected PUF / PIR Panels
Rigid Polyurethane Core (40±2 kg/m³)40mm to 150mm thick rigid panels with continuous tongue-and-groove jointing and concealed fasteners, eliminating cold-bridging for clean rooms and warehouses.
High-Yield Galvalume Sheeting
AZ150 Alloy • 550 MPa Yield StrengthAlu-Zinc 150 GSM coated high-tensile 550 MPa profiled steel sheeting with anti-siphoning capillary grooves preventing leakages under torrential rain.
Daylighting & Natural Aerodynamics
Polycarbonate Sheets & Turbo VentilatorsAero-dynamic continuous throat ridge vents and stainless-steel bearing rotary wind ventilators combined with UV-stabilized 2mm polycarbonate sheets for energy-neutral lighting.
Manufacturing & Continuous Panel Profiling
Heavy fabrication facilities equipped with computerized multi-torch CNC cutting tables and automatic high-pressure polyurethane foaming lines.
CNC Automated Flange Alignment
Flange and web assemblies cut using multi-head CNC plasma cutters, followed by mechanized submerged arc welding for deep uniform penetration.
High-Density Injected Foam Core
Automated continuous polyurethane metering at high pressure prevents thermal voids and achieves uniform 40 kg/m³ insulation density across full length.
100% Bolted On-Site Assembly
Zero hot-works or cutting required on erection field. All primary moments joined using Grade 8.8 / 10.9 high-strength friction grip (HSFG) bolts.
Civil & Structural Design Compliance Sheet
Rigorous engineering benchmarks configured in compliance with national and international building codes.

Turnkey Execution & Quality Assurance Sequence
Zero-compromise non-destructive testing (NDT) and calibration standards applied from mill receipt to final roof ridge sealing.
Raw Material UT & Mill Verification
Every steel plate coil receives Ultrasonic Testing (UT per ASTM A435) for internal lamination defects. Heat number chemistry matched against mill test certificates.
Weld NDT & Dye Penetrant (DPT)
Submerged Arc Welds and critical moment flange-to-web joins tested via Magnetic Particle Testing (MPT) and Liquid Dye Penetrant (DPT) per AWS D1.1 structural welding specifications.
Shop Pre-Fit & Laser Geometry
Sample portal spans pre-assembled on the factory floor using laser distance meters. Hole center-to-center distances, rafter sweep, and flange squaring held within ±1.5mm.
Site Torque & Envelope Sealing
HSFG calibrated torque-wrench testing for bolted moments, continuous lap-screw inspection, thermal envelope scanning for PUF seals, and weatherproofing sign-off.
