What to Know Before You Order
YSL-4000C Industrial Aluminum 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
- Halving the unsupported span roughly triples what a shelf carries, using one extra length of tube and two joints. It is almost always cheaper than upgrading to thicker wall tube for the same result.
- 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.
- 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.
- Published load figures assume the weight is spread across the whole shelf. A fixture or a gearbox sitting in one spot bends the panel several times harder at the same total weight.
- 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
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.
Can you cut to length?
Yes, and cut-to-length delivery removes the squareness risk that comes with site cutting. If you cut on site, use a fine-tooth blade and deburr both ends before assembly.
