Tapered Stiffener Plates – Sniped Gussets for Welding (Packs)
Tapered stiffener plates: right-angle gussets with the sharp tip cut square and a 15 mm corner snipe at the 90° corner, so they sit over the root weld of the joint. Plasma cut from 3, 4 or 5 mm mild steel, 304 or 316 stainless and sold in packs of 4, 10 or 20.
At a glance
- Shape: right-angle triangle with equal legs, square-cut tip and 15 mm 45° corner snipe, no holes
- Sizes: 100, 150, 200, 250 or 300 mm legs, with a 25 to 60 mm flat end
- Packs: 4, 10 or 20 identical plates
- Thickness: 3 mm as standard, 4 mm and 5 mm cost more
- Material: mild steel, 304 or 316 stainless
- Finish: plasma-cut edge, deburred, mill finish (unpainted)
- Made in Knowsley, Merseyside
Need other proportions, a radiused snipe or holes? See custom gusset plates.
Why the snipe and the flat end matter
The corner snipe clears the weld already in the joint, so the stiffener sits tight against both faces. The square-cut tip leaves room to weld round the end and avoids a sharp point. Fabricators use them to stiffen post-to-base-plate joints, brackets, beam ends and frame corners. A set of 4 suits one square base plate.
Choose your material
- Mild steel: the economical choice. Paint, prime or galvanise it for outdoor use.
- 304 stainless: the everyday stainless grade for indoor and sheltered outdoor use.
- 316 stainless: best near the coast, pools, salt or chemicals. 304 vs 316 explained.

Questions
What size is the snipe?
A 15 mm × 45° chamfer at the right-angle corner.
Are they rated for structural loads?
We supply the plates only and make no structural claims. Follow your engineer’s design for load-bearing work.
Are these laser cut?
No. They are plasma cut and deburred, so edges show a plasma-cut finish and are not held to laser-cut tolerances. For tight-tolerance parts, send us a drawing.
