What defines a complex steel structure compared to standard PEB portal frames?

Non-standard geometries, heavy plate thicknesses over 20mm, multi-story industrial plant towers, pipe racks, space frames, and heavy box columns. This is structural steel fabrication that needs specialized 3D BIM modeling and heavy SAW welding, not a standard portal frame.

How does Synergy PEB ensure dimensional accuracy for bespoke structural steelwork?

Every detail gets modeled in 3D BIM before cutting starts, catching clashes on screen instead of on site. It's how proper structural steel fabrication avoids costly rework.

What non-destructive testing standards are applied to heavy steel welds?

100% ultrasonic and radiographic NDT testing on every critical weld, the kind of check any serious steel structure company runs before a component leaves the plant. It's a standard most steel fabrication companies skip to save time.

Can Synergy PEB fabricate heavy pipe racks and industrial plant towers?

Yes. Multi-tier pipe racks, process towers, and heavy box columns are core work for us, not an occasional job. It's what separates a genuine steel fabrication company from one that just does standard sheds — and why clients keep coming back to us for complex work.

Bespoke Heavy Fabrication

Overview — What Are Complex Steel Structures?

A complex steel structure from Synergy PEB covers non-standard industrial steelwork. Heavy plant pipe racks, multi-tier equipment towers, curved roof canopies, and bespoke architectural frameworks. This is the kind of work most companies can't take on. We're a steel structure company built for exactly this kind of steel structure fabrication.

We combine 3D BIM clash detection with automated welding lines to execute heavy plate fabrications up to 50mm flange thickness. Every connection detail, box column, and heavy truss gets pre-assembled at our 70,000 sq. ft. plant. That's what real steel structure fabrication should guarantee — exact site fitment, not on-site guesswork.

Bespoke Architectural Geometry

Curved trusses, large cantilevers, and 3D space frames.

Heavy Industrial Plant Support

Multi-tier process towers and pipe rack structures, backed by real structural steel fabrication experience.

Fabrication Advantages

Key Features & Benefits

Complex steel structures need more than standard fabrication. Real steel structure fabrication at this level means superior load bearing, dimensional accuracy, and architectural versatility. It's what defines steel structure fabrication done right for heavy industrial projects.

Bespoke Architectural Geometry & Heavy Engineering

Custom structural steel tailored for complex designs

Custom structural steel tailored for complex designs. Intricate drawings become precision-fabricated steelwork through careful structural steel fabrication. Not every steel fabrication company can do this kind of work at scale.

High-Tonnage Heavy Plate SAW Welding

Continuous Submerged Arc Welding up to 50mm plate

Continuous Submerged Arc Welding up to 50mm plate. Heavy plate columns, box girders, and primary node connections are joined with automated welding, then checked with 100% Ultrasonic NDT inspection.

3D BIM Structural Modeling & Clash Detection

Zero-error millimeter fabrication accuracy

Zero-error millimeter fabrication accuracy. Advanced 3D BIM modeling maps every bolt hole, gusset plate, and member geometry before plant cutting starts. That's what separates a serious steel fabrication company from one that fixes problems on-site.

Severe Load & High-Seismic Resilience

Engineered to BIS & AWS welding standards

Engineered to BIS and AWS welding standards. Built to sustain severe dead, live, thermal, dynamic, and high-velocity wind loads, in extreme industrial and seismic locations across India.

Precision Capabilities

Specifications & Capabilities

Every heavy steel component gets custom detailed with 3D BIM software, as part of our steel structure fabrication process. As a steel structure company, we run strict quality management at our 70,000 sq. ft. plant.

Heavy Plate Steel Grades

IS 2062 E350 / E450 & ASTM A572

High-tensile steel plates up to 50mm thickness, cut with CNC fiber laser equipment. The kind of precision a real steel structure company — and a serious steel fabrication company — builds a reputation on.

Automated Welding Process

Continuous SAW & GMAW / FCAW

Submerged arc welding on automated lines, with 100% NDT Radiographic and Ultrasonic testing.

3D BIM Detailing

Tekla Structures & 3D Clash Detection

Zero-clash structural detailing, ensuring accurate bolt hole alignment and node geometry.

Complex Frame Geometries

Curved Trusses & Heavy Box Columns

Custom built-up box sections, heavy portal frames, pipe racks, and multi-story plant towers — work that separates a true steel fabrication company from a standard shed builder.

Design Standards

IS 800:2007, AWS D1.1, AISC 360

Engineered to strict Indian and international codes, for extreme dynamic and seismic loads — a standard of structural steel fabrication not every company follows.

Surface Protection & Finishing

SA 2.5 Shot Blasting + High-Build Primer

Manual Shot Blasting, then zinc silicate or epoxy painting, for maximum corrosion defence.
