Aluminum curb ramps with a diamond tread-plate deck. Solid sheet construction with a raised diamond pattern delivers the highest capacity and the longest service life in the B&P ramp line — the CRU3030 model is rated 750 lb at 30″ x 30″ with 3/16″ deck thickness.
The tread plate construction starts with a 3/16″ aluminum sheet stamped with a raised diamond pattern. The diamond ridges are integral to the sheet — not welded on — so concentrated point loads from pallet jack wheels or hand-truck wheels distribute across the diamond surface instead of pushing on a single line of fasteners. That’s why a 30″-square tread plate ramp holds 750 lb where a punched-deck of the same size tops out around 500 lb.
Underneath the deck, B&P uses bent-leg construction for the support frame. The frame transfers load from the deck down to two contact lines on the floor — one at the curb edge, one back from the curb. This is the only ramp geometry in the B&P line that handles pallet jacks safely; smaller-wheel hand trucks work on any of the ramps but pallet jack wheels exert 4–6x the per-square-inch load of a hand truck wheel.
The handle underneath the deck doubles as a curb stop — when the ramp is placed against the curb, the handle wedges against the curb face so the ramp doesn’t kick out under wheel pressure. CRU models use riveted handles (aluminum rivets through the deck into the handle bracket) for lower weight and easier field repair. CR models use welded handles for slightly higher rigidity at the trade of weight and field-repairability.
Practical recommendation: pick CRU for ramps that move daily with your route. Pick CR for ramps that live in one spot for a year or longer. The strength difference is minimal in normal use, but the weight savings of CRU pays off on daily transport.
The CRU2727 (27″ x 27″) holds about 600 lb and is the right pick for standard 4–5″ curb heights with hand truck traffic. The CRU3030 (30″ x 30″) holds 750 lb and is the workhorse — right for 6″ curbs and mixed hand-truck/pallet-jack traffic. Larger sizes go up to 36″ x 36″ for industrial dock plates, but at that size you should consider a permanent dock plate or leveler instead of a curb ramp.
Two situations: (1) higher capacity needed — tread plate at any given size rates higher than the punched-deck equivalent because the diamond pattern is integral, not pierced through, (2) pallet jack traffic — the concentrated load of pallet jack wheels needs solid-deck support, not the holed surface of a punched ramp. For everyday hand-truck use, either deck works and you should pick by drainage need (punched if wet, tread plate if dry).
