Perforated Steel Shelf Panels — 50% Open Decking That Passes Your Fire Inspection

Formed C-channel perforated deck panels for pallet racking, shelving systems and rivet rack units.

14-gauge deck with 1" perforations,

reinforcing channels to fit 1-5/8" step beams,

1-1/2" waterfall returns — custom sizes cut to your beam pitch, not to ours.

Trust bar :

≥50% open surface area — built for NFPA-style sprinkler penetration requirements

Load rated up to [3,000] lbs per deck, tested configuration documented

1.2 / 1.5 / 2.0 mm and 14-gauge deck, [36" / 42" / 48"] depths in stock pattern

Formed and hemmed with zero-weld construction — no weld porosity, no rework

The Decking Decision That Decides Your Inspection Result

Rack decking is the cheapest line item on a warehouse project and the fastest way to fail an inspection.

Drop in a solid shelf deck and you

block the overhead sprinkler system from reaching the tiers below. Fit wire decking and your loose cartons,

small parts and bagged goods

fall straight through the grid.

Perforated steel deck solves both problems in one panel. A punched pattern delivers 50% or greater open

area, so sprinkler water passes

through to lower levels — while the flat steel surface still supports non-palletised loads that wire mesh

cannot hold. The panel is formed

into a C-channel on both sides, with the free edge closed into a hem, so stiffness comes from geometry

rather than welding.

We manufacture these panels to your beam pitch and depth, in cold rolled steel, pre-galvanized or

powder-coated finish. Send your rack

layout and load requirement, and we will return a panel drawing and a rated load figure — not a

generic catalogue size.
