Why Modern PEB Manufacturers Rely on SAIL & JSPL Parallel Flange UB / UC
For decades, conventional Indian construction depended on tapered-flange standard beams (ISMB). However, leading Pre-Engineered Building (PEB) manufacturers, structural consultants, and infrastructure EPC contractors have shifted decisively toward Parallel Flange Universal Beams (UB) and Universal Columns (UC) produced by primary mills like JSPL (Jindal Steel & Power Ltd) and SAIL (Steel Authority of India Ltd).
As leading SAIL & JSPL UB / UC suppliers in Surat, New Bengal Steels stocks the full spectrum of section depths from 200 mm to 900 mm. These parallel flange profiles conform to IS 12778 and structural steel grades IS 2062 E250 / E350 BR, offering significant engineering advantages over both conventional rolled joists and welded built-up sections.
Engineered Advantage: Parallel Flange UB/UC vs. Conventional ISMB Joists
- Uniform Flange Thickness: Parallel inner and outer flange surfaces eliminate the need for tapered washers, significantly cutting bolting and assembly time.
- Higher Strength-to-Weight Ratio: Concentrating steel mass in the outer flanges achieves a higher section modulus (Zxx) per kilogram of steel, resulting in 12% to 20% overall structural weight savings.
- Superior Lateral Torsional Buckling Resistance: Universal Columns (UC) boast substantially wider flange widths (b/D ratio ~ 1.0), delivering outstanding radii of gyration along the minor (Y-Y) axis to resist heavy axial compressive buckling loads.
- Reduced Welding Inspection Costs: Utilizing ready-rolled hot universal sections eliminates longitudinal fillet weld passes required for built-up H-beams, eliminating internal weld shrinkage stresses.

Meeting the Fast-Turnaround Needs of PEB Manufacturers
Pre-Engineered Building manufacturers operate under tight delivery milestones. A delay in securing critical rafter profiles or crane runway beams can halt site erection. New Bengal Steels addresses this by maintaining:
Immediate Sachin Stockyard Dispatch
Direct access to standard 11.5m and 12m lengths ready for dispatch within 24 hours of purchase order confirmation.
Mill Test Certificates (MTC)
Original physical MTCs from SAIL or JSPL with 100% heat numbers matching the stamped heat markings on each beam flange.
Cut-To-Length & Beam Profiling
Custom saw-cutting to exact engineering drawing lengths reduces on-site fabrication scrap and transportation bottlenecks.
Certified Weighment
Electronic computerized weighbridge slips generated at our Sachin facility ensure 100% transparency.
