Steel bullet traps do require scheduled cleaning as rounds hitting steel create lead and dust deposits that are not as prevalent on rubber type bullet traps. Access space behind steel bullet traps is required in order to remove collected lead deposits or allow for a lead removal system to operate. On very high-volume ranges, additional dust collection systems (in addition to standard range ventilation) may be required. Periodic inspection of the steel plates and round deacceleration chambers must be checked for wear and any type of deformation. Ammunition inspection procedures at range check-in must be put in to place to ensure accepted calibers are used and armor piercing rounds are not present.
