What to Know Before You Order
Black Steel Lean Pipe is the structural element of a modular tube system — 28 mm outside diameter, coated steel core, cut and joined on site with hand tools. What it is asked to do is carry load across a span, and that is where most specification mistakes are made.
Allowable load falls sharply with span: our 28 mm lean pipe load rating tables give the figures for each wall thickness and span, with the deflection limit and safety factor stated so the arithmetic can be checked.
Points that decide whether it works
- Ask for the mill certificate when the tube is going into a structural application. Wall thickness tolerance varies between suppliers and it is the figure that governs everything else.
- For electronics work, specify dissipative coating with surface resistivity in the 10^6 to 10^9 ohm range, and confirm the joints, casters and worktop belong to the same grounded path.
- Chrome-plated and plain steel pipe exist for different reasons: plated for appearance and light corrosion resistance, plain for painting or where weld-in fittings are used.
- Capacity is governed by span far more than by wall thickness. Past roughly one metre of unsupported span the limiting factor stops being steel strength and becomes acceptable deflection, which is why thicker tube buys less than buyers expect.
- Cut tube square and deburr before assembly. An out-of-square cut loads the joint unevenly and shows up later as a frame that will not sit flat.
Frequently Asked Questions
How much weight can 28 mm lean pipe hold?
It depends on span. As a working guide, 0.8 mm wall tube spanning 1200 mm carries around 34 kg under an L/200 deflection limit, while the same tube at 600 mm carries about 96 kg. Our load rating tables give the full matrix by wall thickness and span.
Which wall thickness should I choose?
Choose by span first, then by load. If the unsupported distance is over a metre, adding a support usually beats buying thicker tube — the cost is lower and the stiffness gain is larger.
Is the coating available in ESD?
Yes, with surface resistivity in the 10^6 to 10^9 ohm range. Specify it at enquiry stage; retrofitting means replacing tube rather than adding an accessory.
