Plank Grating LHD

Application

Transformer station bunds.

Description

Used in industrial applications as transformer platforms, offshore oil and natural gas drilling rigs requiring low hole density to limit the amount of oxygen and thus starve the source of the fire. Also used in public areas such as balconies. Tested and approved by SP Borås 2015. Safety grating Type LHD® is applied where a slip resistant and flame retardant surface is required - often on oil and gas rigs and trafo stations. Several tests proves that steel filters with LHD® gratings extinguishes oil fires significantly faster than traditional stone filters of macadam, pitl and stone. The surface pattern has less than five percent of air passage.
