Steel Grating Container Loading Calculator

Calculate exactly how many steel grating panels fit in a 20ft GP, 40ft GP, or 40ft HC container. Checks both volume (stacking height) and weight payload to find the actual limiting factor for your shipment.

Container Type

20' GP

5,900×2,350×2,390mm Payload: 27,600 kg

40' GP

12,000×2,350×2,390mm Payload: 26,500 kg

40' HC

12,000×2,350×2,700mm Payload: 26,500 kg

Container Internal Dimensions Reference

Type	Int. Length	Int. Width	Int. Height	Max Payload
20' GP	5,900 mm	2,350 mm	2,390 mm	27,600 kg
40' GP	12,000 mm	2,350 mm	2,390 mm	26,500 kg
40' HC	12,000 mm	2,350 mm	2,700 mm	26,500 kg

Panels are loaded flat (bearing bars vertical). Stack height per layer = bearing bar height + dunnage gap. Orientation optimized for maximum panels per layer.
