Prime Structural Steel
Sections & Heavy Plates
(EN 10025-2 S275JR & S355JR)
Direct mill allocation of prime hot-rolled structural steel sections (Universal Beams, Universal Columns, IPE, HEA, HEB, PFC channels, angles) and heavy commercial plates (6mm–150mm). Engineered for high-rise steel frameworks, long-span bridges, industrial warehousing, and offshore infrastructure. Delivered on chartered breakbulk vessels (CIF/CFR) with 100% independent SGS inspection.
Heavy Structural Profiles & Steel Plates for
Civil Frameworks, Bridges & Heavy Fabrication.
In heavy structural engineering, structural integrity depends directly upon yield uniformity, flange squareness, tight dimensional straightness, and verified notch toughness under dynamic stress. Whether fabricating multi-tier commercial skyscraper frames, long-span highway bridge girders, or offshore marine platforms, mill-certified steel profiles prevent structural distortion, brittle fracture, and fabrication delays.
Asia & Africa General Trading delivers continuous prime allocations of hot-rolled structural steel sections—including European IPE, HEA, and HEB beams, British Universal Beams (UB) and Universal Columns (UC), Parallel Flange Channels (PFC), and equal/unequal structural angles—alongside heavy structural steel plates ranging from 6mm to 150mm. Sourced directly from premier integrated blast furnace (BOF) and electric arc furnace (EAF) mills, every parcel adheres to strict EN 10025-2 (S275JR, S355JR, S355J2+N) and ASTM A36 / A572 Grade 50 standards.
Backed by 20+ years in international commodity trading, our operations desk manages chemical ladle verification, sub-zero Charpy impact testing, ultrasonic plate screening, and chartered vessel breakbulk shipping straight to your discharge seaport.

Need Higher Steel Grades, Z-Direction Testing, or Extra Heavy Plates?
Our direct mill agreements accommodate specialized project requirements beyond standard commercial grades. We arrange dedicated melt and rolling campaigns with custom mechanical impact temperatures, through-thickness testing (EN 10164 Z15/Z25/Z35), ultrasonic lamination checks (EN 10160 Class S1/E1), and surface preparation (shot blasting SA 2.5 with weldable holding primer).
Common Applications & Downstream Uses
Our prime structural beams, columns, channels, and heavy steel plates serve as foundational structural members for commercial skyscrapers, industrial logistics facilities, bridges, and maritime infrastructure across international trade corridors.
01
Skyscrapers & Commercial High-Rise Frames
Heavy universal columns (UC 305 to 356) and wide-flange beams (HEA / HEB 300 to 1000) form the primary vertical and horizontal skeleton of modern commercial skyscrapers, delivering high stiffness and certified seismic ductility.
02
Industrial Warehouses & Portal Frames
IPE beams (IPE 200 to 600) and parallel flange channels (PFC) provide lightweight, high-moment-capacity rafters and stanchions for clear-span industrial distribution hubs, aircraft hangars, and automated logistics warehouses.
03
Highway Bridges & Viaduct Superstructures
Grade S355J2+N and S355K2 heavy plates (20mm to 80mm) are fabricated into composite box girders and plate girders for highway overpasses and railway viaducts, engineered to withstand intense dynamic cyclic fatigue and sub-zero temperatures.
04
Offshore Platforms & Marine Structures
High-strength S355ML thermo-mechanically rolled steel plates with Z25/Z35 through-thickness reduction of area prevent lamellar tearing across heavy node welds in offshore drilling platforms, jetty pilings, and harbor dolphins.
05
Heavy Crane Runways & Factory Gantries
Extra-heavy universal beams (UB 610 to 914) and heavy base plates support continuous 50-to-150 ton overhead traveling crane runways in steel manufacturing mills, shipyards, and heavy machinery production bays.
06
Heavy Storage Tanks & Pressure Equipment
Pressure-vessel and boiler-quality structural plates (P265GH, P355NH, ASTM A516 Grade 70) undergo precision cold roll-forming for bulk petroleum storage tanks, chemical reactors, and industrial autoclave shells.
Four Pillars of Structural Quality Verification
Every shipment is independently verified by recognized international inspection agencies prior to vessel departure, providing complete commercial and metallurgical security for enterprise procurement teams.
Spectrometer Ladle Chemical Analysis
Every cast heat undergoes multi-point optical emission spectrometry to confirm exact carbon (C), manganese (Mn), phosphorus (P ≤ 0.025%), sulfur (S ≤ 0.025%), and nitrogen control, ensuring low carbon equivalent values (CEV ≤ 0.45%) for crack-free field welding.
Mechanical & Sub-Zero Charpy Testing
Calibrated universal tensile machines verify minimum upper yield strength (Re ≥ 355 MPa) and elongation. Impact specimens are subjected to Charpy V-notch fracture tests at +20°C, 0°C, and −20°C to verify 27J minimum impact energy for cold-weather structural safety.
Ultrasonic Flaw & Lamellar Scanning
Heavy structural steel plates (t ≥ 20mm) undergo 100% automated or manual ultrasonic grid scanning per EN 10160 (Class S1/E1) and ASTM A578 to ensure zero internal laminations, non-metallic inclusion clusters, or shrinkage voids prior to vessel loading.
100% Independent SGS / Intertek Load-Port Survey
Independent international surveyors (SGS / Intertek) inspect every parcel at the load-port quay. Surveyors confirm heat numbers, piece markings, flange squareness, web camber, dimensional tolerances, and execute a certified draft survey for contract payment release.
