Structural steel, pipe fabrication, sheet metal and custom assemblies from our Rawalpindi facility. Certified welders, ISO-aligned QC, in-house NDT, and onward delivery to every major Pakistani city.
Metal fabrication in Pakistan is the process of cutting, bending, welding and assembling raw metal stock - plate, sheet, pipe, structural sections and bar - into finished components, sub-assemblies and complete structures. It sits between primary metal production (Pakistan Steel Mills, Tuwairqi Steel, and the rolling mills of Faisalabad and Lahore) and end use in construction, oil & gas, power generation, industrial plants, transport and infrastructure.
Pakistan's fabrication market has historically been split between two extremes: very large EPC-grade fabricators (Descon, Izhar, Heavy Mechanical Complex Taxila) handling refinery and power-plant scope, and thousands of small workshops doing piece-meal welding work in Lahore Misri Shah, Karachi SITE, Gujranwala and Faisalabad. The gap in the middle - quality-driven medium-volume fabrication for industrial sheds, PEB structures, plant utilities and custom equipment - is where Unitec Trade Line operates from our Rawalpindi facility, serving the Islamabad / Rawalpindi / Taxila / Hattar industrial belt and onward to Lahore, Multan, Peshawar and Karachi via road freight.
We are vertically integrated: drawings produced in our Design & Development desk, materials sourced through our Import & Export network including imported plate and specialty alloys, fabrication completed in-house with certified welders, NDT-backed quality release, and delivery handled by our Freight & Logistics team. That single accountability chain is the difference between a job shop and an engineering partner.
I-beams, H-columns, trusses, purlins, bracing, base plates, gusset plates, complete structural assemblies. Meets Pakistan building code and international standards. All projects begin with detailed engineering drawings.
Piping spools, manifolds, headers, complete piping systems for industrial plants, oil and gas, utility infrastructure. Carbon steel, stainless steel, alloy pipes from 1/2 inch to 48 inches.
Cutting, bending, punching, rolling, forming. Enclosures, panels, guards, chutes, hoppers, ductwork from mild steel, stainless steel, aluminum, galvanized sheets. Combined with our CNC machining for precision-fit components.
MIG, TIG, arc, flux-core welding. Structural welding, pipe welding, pressure vessel welding, specialty welding. All procedures qualified and documented per applicable codes.
Steel stairs and railings, platforms and walkways, tank and vessel fabrication, equipment skids and frames, material handling equipment, architectural metalwork. Specialty materials sourced from international suppliers when project specs demand them.
Mild steel (all grades), stainless steel (304, 316, 316L), aluminum (6061, 5052), galvanized steel, Corten weathering steel, specialty alloys. Certified suppliers with mill test certificates; specialty alloys and international materials sourced on demand for projects that require them.
We work with the full range of construction- and industrial-grade metals available in Pakistan, plus imported specialty alloys when project specs demand them. Every steel input arrives with a Mill Test Certificate (MTC) traceable to the manufacturing lot - we do not accept un-certified scrap-rerolled material, which is the silent quality issue plaguing much of the local market.
| Material | Common Grades | Typical Uses |
|---|---|---|
| Mild Steel (MS) | A36, S275, A572 Gr. 50, BS 4360 / EN 10025 | Structural framing, base plates, brackets, equipment skids |
| Stainless Steel (SS) | 304, 304L, 316, 316L, 321, 410 | Tanks, vessels, food/pharma contact, chemical piping, architectural cladding |
| Galvanized Iron (GI) | Hot-dip per ASTM A123/A153, BS EN ISO 1461 | Outdoor structures, ducting, transmission line accessories, agricultural sheds |
| Aluminum | 6061-T6, 5052-H32, 6063, 1100 | Lightweight structures, HVAC ducting, architectural screens, electrical enclosures, bus bars |
| Copper & Brass | C11000 ETP, C26000, C36000 | Electrical bus bars, earthing strips, plumbing fittings, decorative metalwork |
| Specialty Alloys | Corten A588, Hardox 400/450/500, Inconel, Duplex SS | Wear plate, weathering steel, oil & gas / chemical service (imported via our network) |
We cut plate, sheet and section using the right process for the thickness and edge-quality requirement:
All welders are qualified per ASME Section IX or AWS D1.1 with current certifications. Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) are on file for every joint type, material thickness and position we run.
Quality is non-negotiable. Our QA/QC system aligns with the following standards and we operate to whichever is most stringent for a given client contract:
Every job is inspected at four mandatory hold points: incoming material (MTC verification + dimensional check), fit-up (before tack-welding), in-process welding (visual + measurement during deposition), and final dispatch (dimensional, coating, packing).
Every project ships with a documentation dossier containing mill test certificates, weld maps, NDT reports, paint / coating DFT readings, dimensional inspection records, and a signed fabrication completion certificate - auditable and ready for client or third-party review.
Small jobs (1–3 tonnes, simple drawings): 7–10 working days. Medium PEB and shed work (10–50 tonnes): 4–6 weeks including shop drawings and primer painting. Larger piping spools or pressure-class vessels: 6–10 weeks. Lead time accelerates significantly when drawings are issued at order; if we have to develop drawings ourselves it adds 1–2 weeks.
No fixed MOQ. We have run jobs from a single 200 kg architectural staircase up to 200-tonne PEB structures. Below approximately 500 kg we charge a setup fee to cover drawing review, machine setup and minimum welder time.
Ideally GA drawings, sectional details and a bill of materials with material grades. If you only have concept sketches, photos or written specs, our Design & Development desk produces shop drawings - that adds 1–2 weeks to the schedule but ensures clean fabrication and accurate quoting.
Yes - we handle last-mile delivery to all major Pakistani cities. Truck cost depends on dimensions and tonnage and is quoted transparently as a separate line on the invoice. Oversize and over-height loads are moved with NHA route clearance arranged in advance.
Painting (epoxy, polyurethane, zinc-rich) is in-house. Hot-dip galvanizing is subcontracted to certified plants in Lahore or Karachi - we manage the round-trip including transport and re-inspection on return.
Standard schedule: 30% advance on order confirmation, 60% before dispatch from our shop, 10% after delivery and acceptance. Larger projects move to milestone-based progressive billing tied to material procurement, fit-up and dispatch.
