Structural Fabrication & Erection
Kooheji Constructions LLP & Singh HP Group delivers complete structural fabrication and erection services for heavy industrial plants, oil & gas facilities, refineries, and infrastructure projects. Our structural teams handle everything from raw steel fabrication in our workshops to precise site erection — ensuring every structure is built to exact engineering specifications and international codes.
With a dedicated structural engineering team, certified welders, and experienced erection supervisors, we fabricate and erect heavy steel structures that form the backbone of industrial plants — from pipe racks and equipment supports to full steel building structures and technological platforms.
What We Fabricate & Erect
From heavy steel fabrication in our workshop to precise site erection — complete structural solutions for industrial facilities.
Heavy Structural Steel Fabrication
We fabricate heavy structural steel components including beams, columns, trusses, bracing, and connection plates for large-scale industrial facilities, process plants, and infrastructure projects.
All structural fabrication is carried out in our workshops using modern cutting, bending, and welding equipment — with certified welders, weld inspection, and dimensional checks at every stage to ensure components are fabricated precisely to approved drawings and international structural codes.
Pipe Racks & Pipe Supports
Pipe racks are the primary structure that carries process piping, cable trays, and utility lines across industrial plants. We design, fabricate, and erect multi-tier pipe rack structures built to handle the full weight and thermal expansion loads of the piping systems they support.
Our pipe rack structures are engineered and fabricated to AISC and client-specified standards — with all connection details, anchor bolts, and base plates fabricated to exact engineering requirements for reliable long-term performance.
Platforms, Walkways & Staircases
Safe and reliable access to equipment, vessels, and elevated process areas is essential in any industrial plant. We fabricate and erect structural steel platforms, walkways, handrails, and staircases that provide safe access while meeting all applicable structural and safety standards.
All platforms and walkways are designed with proper grating, handrail heights, and load-bearing capacity as per engineering specifications — ensuring full compliance with HSE requirements and operational safety for plant personnel.
Equipment Support Structures
Heavy industrial equipment such as vessels, heat exchangers, tanks, compressors, and air coolers require dedicated structural support frames that can safely carry their full operating weight, wind loads, and seismic loads.
We design, fabricate, and erect custom equipment support structures for all types of static and rotating equipment — ensuring every support is precisely engineered and installed to carry the specified loads with full safety factors and long-term structural integrity.
Technological Structures
Technological structures are specialized steel structures designed to support and house specific industrial processes, equipment arrangements, and operational requirements within a process plant.
We fabricate and erect technological structures for furnaces, reactors, columns, flare structures, cooling tower support frames, and other process-specific structural requirements — all engineered and built to precise dimensional and load requirements.
Steel Building Structures
We fabricate and erect complete pre-engineered and custom steel building structures for industrial facilities including warehouses, compressor buildings, substations, control rooms, maintenance workshops, and storage facilities.
Our steel building structures are engineered for the specific industrial environment — wind loads, seismic requirements, crane loads, and operational requirements — and erected with precision using certified structural erection teams and heavy lifting equipment.
Our Fabrication & Erection Process
From engineering review to final inspection — a proven process delivering precise and reliable structural works every time.
Engineering & Drawing Review
Detailed review of structural general arrangement drawings, connection details, material specifications, and fabrication standards before shop work begins.
Material Procurement & Inspection
Procurement of certified structural steel sections, plates, and fasteners with mill test certificates. Incoming material inspection and heat number traceability maintained throughout.
Shop Fabrication & Welding
Precision cutting, fitting, and welding of structural components by certified welders in our fabrication workshop. Dimensional checks and weld inspection at every stage.
Surface Preparation & Coating
Shot blasting and application of primer and finish coats as per project coating specification — ensuring long-term corrosion protection of all fabricated structural members.
Site Erection & Alignment
Systematic structural erection using certified cranes and rigging equipment. Precise alignment, leveling, and bolting of structural members as per approved erection sequences.
Final Inspection & Handover
Dimensional survey, bolt torque verification, weld inspection, and coating touch-up before final structural inspection and documentation handover to the client.
