28mm Modular Pipe Load Capacity, Wall Thickness (0.7mm–2.0mm) & Span Deflection Guide
How to select pipe wall thickness (0.7mm, 1.0mm, 1.2mm, 2.0mm), calculate maximum unsupported span, and reinforce heavy-duty modular racks using parallel double-pipe bracing.
- 28 mm
- Standard Outer Diameter
- 0.7–2.0 mm
- Steel Wall Thickness Range
- 2.2x
- Strength Gain with Double-Pipe Bracing
- < L/200
- Recommended Max Deflection
Executive Summary & Engineering Takeaway
A single 28mm D-coated steel pipe with 1.0mm wall thickness supports approximately 75 kg Center Point Load (or 150 kg Uniformly Distributed Load) across a 1,000 mm span; upgrading to 2.0mm wall thickness or adding a parallel double-pipe truss with HJ-6 joints more than doubles the load capacity while keeping deflection under L/200.
1. Choosing the Right Wall Thickness for Your Load
Selecting the right pipe thickness prevents over-engineering light structures and prevents sagging on heavy flow racks:
- 0.7 mm / 0.8 mm (DP2807): Ideal for 5S visual boards, light document holders, shadow foam frames, and empty-box return lanes.
- 1.0 mm / 1.2 mm (DP2810 / DP2812): The industry workhorse for standard assembly workstations, kitting carts, and carton FIFO flow racks.
- 2.0 mm (DP2820): Heavy-duty structural posts, long-span beams, and high-payload tugger train trolleys.
Approximate Load Capacity Over a 1,000 mm Span (Single 28mm Pipe)
| Pipe Model / Thickness | Point Load (Center) | Uniform Distributed Load (UDL) | Recommended Application |
|---|---|---|---|
| DP2807 (0.7 mm Steel) | ~45 kg | ~90 kg | Visual boards, light shelves & dividers |
| DP2810 (1.0 mm Steel) | ~75 kg | ~150 kg | Standard workstations & tote flow racks |
| DP2812 (1.2 mm Steel) | ~95 kg | ~190 kg | Heavy kitting carts & multi-bay FIFO racks |
| DP2820 (2.0 mm Steel) | ~155 kg | ~310 kg | Heavy-duty uprights & high-load base frames |
