Metal tube fabrication refers to the process of cutting, forming, bending, and welding metal tubes to create custom assemblies for structural, mechanical, and pressure-bearing applications. It combines precision laser cutting, cold or hot rolling, CNC bending, and welding to produce tubes in carbon steel, stainless steel, and aluminium to exact customer specifications and tolerances.
Metal tube fabrication consists of four core operations that transform raw tube stock into finished assemblies:
Tube Laser Cutting — Fiber laser systems cut profiles, holes, and end-cuts on tubes with positional tolerances of ±0.1 mm. This process handles complex geometries and achieves high repeatability across batches.
Tube Rolling — Flat sheet or bar stock is formed into round, square, or oval tube profiles using hydraulic or CNC rolling equipment. This enables custom cross-sections for structural frames and non-standard applications.
CNC Tube Bending — Rotary draw or push-bending machines bend tubes to precise angles without wall collapse or spring-back distortion. Used for hydraulic lines, exhaust systems, and handrails.
TIG/MIG Welding — Tungsten inert gas and metal inert gas welding join tube sections to EN ISO 5817 weld quality level B. TIG is applied to stainless steel and thin-wall sections; MIG handles carbon steel structural assemblies at higher deposition rates.
Entag processes carbon steel grades S235 and S355 (EN 10210 structural tube), stainless steel AISI 304 and AISI 316, and aluminium alloys. Wall thickness spans 0.5 mm to 12 mm depending on material and section geometry. Tube laser cutting holds ±0.1 mm positional tolerances on cut profiles and hole locations—sufficient for automotive, HVAC, oil and gas, and precision mechanical assemblies. Engineers specify these tolerances on technical drawings, and Entag's team advises on material selection based on corrosion environment, load-bearing requirements, and operating temperature before quoting.
Custom tube fabrication supports diverse sectors. In Egypt, HVAC manufacturers and mechanical fabricators rely on welded tube assemblies for ductwork, structural frames, and hydraulic supports. In Saudi Arabia, oil and gas infrastructure projects specify tube fabrication for pipe supports, skid frames, and pressurized vessel components. Automotive and heavy equipment suppliers across both regions use laser-cut and bent tubes for exhaust manifolds, roll cages, and suspension links. Entag consolidates laser cutting, rolling, bending, and welding under one roof, eliminating the need to coordinate multiple subcontractors. Complementary work like sheet metal fabrication in Egypt and CNC machining services in Egypt are also available on the same platform.
What is the difference between a tube and a pipe in metal fabrication?
A tube is specified by outer diameter and wall thickness for structural or mechanical use. A pipe is sized by nominal bore and designed to convey fluids or gas under pressure. Entag fabricates both in carbon steel, stainless steel, and aluminium to customer drawings and applicable standards (EN 10210 for structural tube, ASME B36.10 for pipe).
What metals can be used in tube fabrication?
The most common materials are carbon steel grades S235 and S355 (EN 10210), stainless steel grades AISI 304 and AISI 316, and aluminium alloys 6061 and 5083. Carbon steel offers cost-effectiveness for structural frames, stainless steel provides corrosion resistance for HVAC and offshore applications, and aluminium reduces weight for aerospace and automotive assemblies. Entag's team advises on material selection before quoting.
What tolerances can metal tube laser cutting achieve?
Tube laser cutting holds positional tolerances of ±0.1 mm on cut profiles and hole locations. Wall thickness capability ranges from 0.5 mm to 12 mm depending on material and section size. Bevel cuts and chamfers are also held to ±0.1 mm, making this process suitable for structural, automotive, HVAC, and precision mechanical assemblies requiring tight dimensional control.
How long does custom tube fabrication take in Egypt?
Standard laser-cut and welded tube assemblies typically complete in 3–7 business days from confirmed drawings. Entag operates as an on-demand platform, so parts are quoted within 24 hours of CAD upload and production begins immediately on order confirmation.
What welding standards does Entag follow for tube fabrication?
Entag's tube welding references AWS D1.1 for structural applications and EN ISO 5817 weld quality level B for general fabrication. TIG welding is used for stainless steel and thin-wall sections requiring clean, low-distortion joints. MIG welding is applied for carbon steel structural tube assemblies at higher deposition rates.
Can Entag supply tube fabrication services to companies in Saudi Arabia?
Yes. Entag supplies fabricated tube assemblies to clients in Jeddah, Riyadh, and Dammam. Engineering teams can upload drawings through entag.co, receive a quote within 24 hours, and have finished parts shipped directly to site.
