Section & structure mills

Precision-engineered section and structure rolling mills

From light angles to heavy I-beams — GPRM designs, manufactures, and commissions rolling mills for the complete range of structural steel profiles, from 20mm to 600mm.

Overview

The foundation of our expertise

Section and structure rolling mills are where GPRM's story began — and they remain our core strength. With over three decades of experience designing pass sequences, optimizing roll profiles, and commissioning mills across India and overseas, we bring a depth of knowledge that few manufacturers can match.

Our section mills are capable of producing the full spectrum of structural profiles: angles, channels, I-beams, H-beams, flats, rounds, and squares. Each mill is designed from the ground up to match your specific production targets, site conditions, and market requirements.

Whether you need a light section mill for small angles and channels or a heavy structural mill for large I-beams and H-beams, GPRM delivers a complete solution — from initial pass design through equipment manufacturing, erection, commissioning, and post-commissioning support.

Every mill is built to meet IS, EN, and ASTM standards, ensuring your products are accepted in both domestic and international markets.

Profiles we produce

Structural steel profiles

Our section mills produce the complete range of structural profiles used in construction, infrastructure, and industrial applications.

Angles

Equal and unequal angles for structural framing, towers, transmission lines, and general fabrication.

Size range25mm – 250mm

Channels

Parallel flange and tapered flange channels for structural frameworks, machine bases, and vehicle chassis.

Size range75mm – 400mm

I-Beams

Standard I-beams for building construction, bridges, flyovers, and heavy load-bearing structural applications.

Size range75mm – 600mm

H-Beams

Wide-flange H-beams for columns, heavy structural applications, and industrial building frameworks.

Size rangeUp to 300 × 300mm

Flats & squares

Flat bars and square bars for general engineering, fabrication, agricultural implements, and automotive components.

RangeFull range available

Rounds

Round bars for machining, bright bar production, fastener manufacturing, and downstream forging applications.

RangeFull range available
Rolling process

From billet to structural profile

01
Billet reheating
Billets or blooms are heated to 1100–1200°C in walking beam or pusher-type reheating furnaces.
02
Roughing passes
Initial breakdown of the billet through roughing stands, reducing the cross-section and beginning to form the profile shape.
03
Intermediate & finishing
Progressive rolling through intermediate and finishing stands with precision pass designs to achieve the final profile dimensions.
04
Cooling & cutting
Profiles are cooled on the cooling bed, straightened, and cut to commercial lengths by cold saws or shears.
Applications

Where GPRM structural profiles are used

Building construction

Structural frameworks for residential, commercial, and high-rise buildings using angles, channels, and beams.

Bridges & flyovers

Industrial sheds & warehouses

Pre-engineered building components, portal frames, and structural supports for large-span industrial facilities.

Transmission towers

Angles and structural sections for electrical transmission towers, telecom towers, and wind turbine foundations.

Railway infrastructure

Structural sections for railway station roofing, platform shelters, foot over bridges, and signaling gantries.

Shipbuilding & marine

Structural profiles for ship hulls, offshore platforms, port infrastructure, and marine equipment fabrication.
