Our end-to-end sheet metal capability spans laser cutting, CNC bending, stamping, MIG/TIG welding, sub-assembly, and surface finishing — all governed by stringent quality protocols and delivered to the timelines our customers depend on. Whether you are an automotive OEM sourcing structural brackets, an industrial equipment manufacturer requiring precision enclosures, or a capital goods producer seeking reliable sub-assemblies, Multitek brings the expertise and infrastructure to deliver.
What Are Sheet Metal Fabricated Components?
Sheet metal fabrication is the industrial process of transforming flat metal sheets — typically ranging from 0.5 mm to 10 mm in thickness — into functional, finished components through a sequence of cutting, forming, joining, and finishing operations. The process can handle a wide range of metals including mild steel, stainless steel, galvanised steel, aluminium alloys, copper, and brass, with each material selected to match the mechanical, thermal, and corrosion requirements of the application.
Unlike casting or machining from solid stock, sheet metal fabrication is inherently efficient — material wastage is minimised, and the same process scales seamlessly from prototype quantities to high-volume mass production. The resulting components are strong, dimensionally consistent, and readily integrated into larger assemblies, making sheet metal fabrication the backbone of the automotive, engineering, electronics, HVAC, and industrial sectors.

Our Sheet Metal Fabrication Processes
Multitek’s sheet metal fabrication workflow is fully integrated under one roof, eliminating inter-supplier delays, quality gaps, and communication overhead. Here is how we take your design from raw material to finished component:
| Process | What We Deliver |
|---|---|
| Laser Cutting | CNC laser cutting delivers tight tolerances (±0.1 mm) and clean edges on mild steel, stainless steel, and aluminium up to 10 mm thickness. Complex profiles, apertures, and intricate geometries are cut with minimal heat-affected zones and negligible material waste, making laser cutting our go-to method for both prototype and volume production. |
| CNC Press Brake Bending | Our CNC press brakes produce precise angular bends with tolerances within ±1°, accommodating a wide range of material gauges and bend radii. Consistent tooling setup and programmable back-gauges ensure repeatability across high-volume runs, critical for automotive structural and trim components. |
| Stamping & Punching | High-speed stamping and progressive die tooling enable the rapid, repeatable production of punched blanks, perforated panels, and complex stamped forms. Stamping is our preferred process for high-volume, detail-critical components where per-piece cost must be minimised without sacrificing accuracy. |
| MIG & TIG Welding | Our certified welders and semi-automated welding stations join sheet metal components using MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) processes, selected based on material, joint geometry, and structural requirements. Resistance spot welding is also available for automotive body and bracket assembly applications. |
| Shearing & Blanking | Precision power shearing produces straight, burr-minimal cuts for blanking operations, providing cost-effective material preparation before subsequent forming or welding processes. |
| Drilling & Tapping | CNC drilling and tapping operations add threaded holes, clearance holes, and counter-bores to fabricated components, enabling direct assembly without secondary machining at the customer's end. |
| Sub-Assembly & Integration | Beyond individual components, Multitek assembles sheet metal sub-assemblies — welded frames, bracketed modules, and fitted enclosures — reducing customer-side assembly steps and part handling costs. |
Materials We Work With
Selecting the right base material is as critical as the fabrication process itself. Multitek’s engineering team advises customers on material grade, gauge, and coating selection to optimise performance, longevity, and cost:
Mild Steel (MS) — The most widely used sheet metal material. Excellent formability and weldability, economical, and ideal for structural brackets, frames, enclosures, and automotive body components. Available in HR (hot-rolled) and CR (cold-rolled) grades.
Stainless Steel (SS 304 / SS 316) — Superior corrosion resistance for applications exposed to moisture, chemicals, or food-grade environments. SS 316 offers additional resistance to chlorides, making it the material of choice for marine and chemical processing components.
Galvanised Steel (GI) — Cold-rolled steel with a zinc coating for enhanced corrosion protection without the cost of stainless. Widely used for automotive under-body components, HVAC ducting, and outdoor enclosures.
Aluminium Alloys (6061, 5052) — Lightweight and naturally corrosion-resistant. Essential where weight reduction is a design priority — automotive panels, aerospace brackets, and electronics enclosures. Excellent anodising and powder coating compatibility.
Copper & Brass Sheet — Superior electrical and thermal conductivity; used in electrical busbars, heat exchanger fins, and decorative architectural components.
High-Strength Steel (HSS / HSLA) — For structural automotive components requiring maximum strength at minimum weight, high-strength low-alloy steels deliver performance that standard mild steel cannot match.
Surface Finishing Options
Surface finishing is not merely cosmetic — it is an engineered solution that determines the corrosion life, mechanical durability, and aesthetic quality of a sheet metal fabricated component. Multitek offers a range of finishing options to suit the operating environment and customer specification:
| Finish | Description & Benefits | Best For |
|---|---|---|
| Powder Coating | Electrostatically applied polymer powder cured at high temperature. Provides a hard, uniform, UV-resistant surface with excellent chip and scratch resistance. Available in a wide colour palette. | Automotive trim, industrial enclosures, consumer goods |
| Hot-Dip Galvanising | Steel components are dipped in molten zinc, forming a metallurgically bonded zinc-iron alloy layer. Outstanding corrosion protection for outdoor or harsh environments. | Automotive under-body, structural frames, outdoor hardware |
| Zinc Electroplating | Electrodeposited zinc layer providing moderate corrosion resistance with tighter dimensional control than hot-dip galvanising. Often used with chromate conversion coating. | Fasteners, brackets, automotive components |
| Phosphating | Zinc or iron phosphate conversion coating applied before painting or powder coating. Doubles paint adhesion and enhances corrosion resistance. | Pre-treatment for automotive and industrial painted parts |
| Anodising (Aluminium) | Electrochemical process thickening the natural aluminium oxide layer for superior corrosion resistance and surface hardness. Allows vibrant anodic dye colouring. | Aluminium enclosures, aerospace brackets, decorative parts |
| Painting & Liquid Coating | Wet spray painting applied for complex geometries or where specific industrial or RAL colours are required. Suitable as a standalone finish or over phosphate pre-treatment. | OEM colour-matched components, HVAC, panels |
| Brushing / Deburring | Mechanical surface treatment to remove burrs, sharp edges, and tool marks. Essential for safe handling and fit-up quality in assemblies. | All fabricated components as a standard post-process |
These capabilities are validated against calibrated gauges, CMM measurement, and surface profilometers — not estimations. Tighter tolerances are achievable for specific features and materials; our engineering team discusses application requirements before committing to a tolerance specification.
