Engineering Services in Pakistan

Metal fabrication under one roof in Rawalpindi: structural steel, pipe spools, sheet metal and custom assemblies. Vertically integrated - plate and specialty alloys sourced through our own import desk, structures welded by AWS / ASME-qualified welders, and the same QA dossier follows the job from cutting to dispatch.

Full-Service Engineering in Pakistan - What That Looks Like

Pakistan's engineering services market is split between EPC giants (Descon, HMC Taxila) handling refinery and power-plant scope, and thousands of small workshops doing piece-meal welding or single-machine work. The middle - medium-volume, drawing-driven, quality-documented engineering - is thinly served. That is the gap Unitec operates in.

Our fabrication capability covers the full chain:

  • Cutting & Forming - plasma, oxy-fuel and laser-partner cutting, press-brake bending, section and pipe rolling.
  • Welding & Assembly - SMAW, MIG, TIG and FCAW by AWS D1.1 / ASME IX qualified welders, working to WPS / PQR on file.
  • Finishing & QA - hot-dip galvanizing, painting, in-house VT/PT/MT plus partner UT/RT, and a documentation dossier with every dispatch.

You can buy fabrication on its own, or chain it with our trade desk so material import, fabrication and delivery sit with a single supplier - the difference between an on-time delivery and a finger-pointing exercise.

Frequently Asked Questions

What engineering services does Unitec offer?

Metal fabrication runs from our Rawalpindi shop floor: structural steel, pipe spools, sheet metal, custom assemblies and pre-engineered buildings, with AWS D1.1 / ASME IX qualified welders, in-house NDT and a full documentation dossier on every dispatch.

Can fabrication run alongside your trade services on one project?

Yes - and it often does. A typical combined job: our trade desk imports the plate or specialty alloy, the fabrication bay cuts, welds and finishes the structure, and our freight desk delivers it to site. One delivery manager owns the chain, one inspection dossier covers the whole job.

What materials and quality standards do you work to?

Materials cover the full range: mild steel, stainless (304/304L/316/316L/410/17-4 PH), tool steel (D2/O1/H13), aluminum (6061/7075/5052), brass, copper, GI, Corten, plus imported specialty alloys (Inconel, Hastelloy, duplex SS, titanium). QA is ISO 9001:2015-aligned with welders qualified per AWS D1.1 / ASME Section IX, in-house VT/PT/MT and partner UT/RT NDT.

Do you deliver across Pakistan?

Yes. Last-mile delivery to all major Pakistani cities - Lahore, Faisalabad, Multan, Peshawar, Karachi and Quetta. Truck cost depends on dimensions and tonnage and is quoted as a separate line on the invoice. Oversize and over-height loads are moved with NHA route clearances arranged in advance.

What's the typical lead time on engineering work?

Small fabrication jobs 7–10 working days. Medium PEB and shed work 4–6 weeks including shop drawings. Large piping spools or pressure-class vessels 6–10 weeks. Imported-material jobs add the shipping lead time, quoted up front.
