Who We Are
Expert Bridge Construction Company
Haq Haffiz is a premier Bridge Tringle Core manufacturer and truss bridge construction company in India delivering advanced structural solutions across India. Our Bridge Tringle Core systems use the geometric strength of triangular load distribution, making them suitable for long-span crossings, highway overpasses, railway bridges, and industrial walkways.
With decades of field experience and certified engineering teams, we combine advanced steel fabrication with precision construction methods to deliver bridges that are strong, lightweight, and built to last.
Why choose us
- IS 2062 / IS 800 certified steel structures
- Structural design by IIT-certified engineers
- Pan-India Bridge Tringle Core construction
- Turnkey EPC delivery from design to handover
- Post-installation maintenance support available
What Is Bridge Tringle Core?
Bridge Tringle Core is an advanced structural system where triangular frameworks form the main load-bearing part of a bridge or roof. This geometry distributes forces efficiently and resists tension, compression, and lateral loads at the same time. It is widely used in modern truss bridge and Bridge Tringle Core construction projects.
Main features
- Triangular Force Distribution
Each triangle acts as a rigid unit. Loads move through the sides of the triangles instead of causing bending, which reduces weak points. - High Span-to-Weight Ratio
The truss principle allows long spans, from 20 m to over 200 m, using less material than solid girder systems. - Steel Fabricated Nodes
Welded or bolted node connections improve force transfer, reduce stress concentration, and support modular assembly for faster construction. - Hybrid Design Options
Tringle Core systems can be used with prestressed concrete decks, composite steel slabs, or cable-stay elements for different site needs.
Our Bridge Construction Process
Splitting electrical work across multiple contractors is one of the most common — and costly — mistakes property owners make. Coordination failures, warranty disputes, and finger-pointing when problems arise are the inevitable results.
From concept to commissioning, every Bridge Tringle Core project follows a structured, quality-assured delivery process.
Geotechnical investigation, soil testing, hydraulic analysis, and topographic survey of the site.
Preparation of Detailed Project Reports with load calculations, Bridge Tringle Core geometry, BIM models, and material specifications.
Steel truss members are cut, drilled, and welded under strict quality control as per IS 800 and IRC standards.
On-site erection using cranes and launching systems, followed by load testing, safety inspection, and formal handover.
Types of Truss Bridges We Manufacture
Every Bridge Tringle Core configuration is designed according to span, load, and terrain requirements.
1. Through Truss Bridge
The deck passes through the truss. Suitable for rail crossings and medium-span highway bridges.
2. Pony Truss Bridge
An open-top half-through truss ideal for short to medium highway spans, rural roads, and irrigation crossings.
3. Deck Truss Bridge
Traffic runs on top of the truss. Common for elevated expressways and flyovers.
4. Warren Truss Core
Alternating diagonal members distribute loads evenly. Suitable for long-span pedestrian and vehicular bridges.
5. Pratt Truss Core
Vertical members carry compression and diagonals carry tension. Good for heavy live loads.
6. Howe Truss Core
Reverse diagonal orientation performs well under uneven loading, often used in industrial platforms and conveyor bridges.

Frequently Asked Questions
What is a Bridge Tringle Core system?
 It is the triangular truss framework that forms the main structural spine of a truss bridge. The triangular geometry helps distribute stress evenly, making the structure strong and lightweight.
How long does truss bridge construction take?
 A 30–50 m span usually takes 3–5 months from design finalization to commissioning. Larger spans over 100 m may take 8–18 months.
Which truss bridge type is best for highways?
 Deck Truss and Warren Truss configurations are commonly used for highways because they provide strong load distribution and support heavy traffic.
Do you provide design services along with construction?
 Yes. Haq Haffiz works as a full EPC contractor and handles design, DPR preparation, FEA analysis, fabrication drawings, and construction.
Are your bridge structures anti-corrosion protected?
 Yes. Steel truss structures receive hot-dip galvanization, epoxy primer, and polyurethane top coats. Marine-grade systems are also available for coastal environments.
What is your minimum project span for truss bridges?
 Projects start from 10 m spans for drainage crossings and industrial walkways and go up to 250 m or more for major crossings.
