Workbench Duty Ratings Explained: Medium, Heavy & Super Heavy Duty
Medium duty, heavy duty and super heavy duty are not marketing fluff on a British-made bench — they map to frame steel and UDL. Buyers also search “medium weight”, “heavyweight” and “standard” benches; those phrases usually mean the same job bands as our duty names.
This guide bridges that language to real specifications from our catalogue so you can specify the right frame the first time.
Duty at a glance
| Duty (our name) | What buyers often type | Typical frame | Typical UDL (fixed bench) | Common uses |
|---|---|---|---|---|
| Medium duty | medium weight, light industrial, packing, electronics | 38×38×1.5mm square hollow section | 350kg | Assembly, packing stations, ESD/electronics, stainless prep-style work |
| Heavy duty | heavyweight, heavy duty garage, fabrication | 50×50×5mm angle iron | 1,000kg | Workshops, garages, vices, general fab (mobile variants often 750–1,000kg) |
| Super heavy duty | extra heavy, production bay | Heavy angle-iron construction | 1,500kg | High static loads on a production bench |
| Welding | welding table / welding bench | 50×50×5mm angle iron + plate or perforated top | up to 2,500kg | Hot work, high heat, heavy plate |
Always confirm the figure on the product page for the exact model — accessories, casters and special sizes can change the system rating.
Medium duty — when 350kg is the right call
Medium duty benches use a lighter SHS frame and suit loads that are real but not extreme: line-side assembly, packing, inspection, and electronics (including ESD laminate tops at 350kg UDL). If operators are mostly handling tools and sub-assemblies rather than engines or plate, medium duty is usually the efficient choice — and still fully welded and made in Britain.

Heavy duty — the default for serious workshops
Heavy duty is our workhorse: 50×50×5mm angle iron and typically 1,000kg UDL on fixed benches, with steel or solid wood tops and options for drawers, cupboards and vices. This is the band most “heavyweight workbench” searches should land on.
Mobile heavy duty benches keep the heavy frame language but may rate at 750kg or 1,000kg UDL depending on the wheel set and model — read the product rating, not the category name alone.

Super heavy duty and welding
When static loads climb, super heavy duty (around 1,500kg UDL on the main SHD bench) or a dedicated welding bench (up to 2,500kg UDL with plate or perforated tops) is the honest upgrade. Do not buy a medium duty frame and hope paint thickness will carry plate work.

How to choose without over-buying
- Estimate the heaviest distributed load on the top during normal work.
- Add a margin if loads are uneven or partly concentrated (vices, presses).
- Decide fixed vs mobile — mobility can lower the usable system rating.
- Pick the worktop for the process (steel, wood, laminate, stainless, ESD), not only the frame.
- If 840mm height is wrong for the task, say so — we build to order rather than forcing an adjustable mechanism you will set once.

Frequently asked questions
What is the difference between medium duty and heavy duty workbenches?
On our range, medium duty typically uses 38×38×1.5mm square hollow section at about 350kg UDL. Heavy duty typically uses 50×50×5mm angle iron at about 1,000kg UDL on fixed benches. The jump is real steel and real load capacity, not a badge.
What does heavyweight workbench mean?
Searchers usually mean a heavy industrial bench for garage or fabrication work. In our catalogue that maps to heavy duty (around 1,000kg UDL) or super heavy duty / welding benches for higher loads.
Is super heavy duty always better?
No. If your loads sit in the 350kg band, medium duty is stiffer in use than an oversized frame with the wrong worktop. Buy the duty that matches the job.
Do mobile benches use the same duty names?
Yes, but check UDL on the product — casters can change the system rating even when the frame looks heavy duty.
