1 Hour Fire Rated Store - CS2FR (To Hold 72 Containers With Floor Space) A rolled hollow welded frame creates a strong structure for this fire rated drum store. The walls, 1250mm wide hinged-doors and roof have been in-filled with Rockwool Firebatt insulation and covered with sheet steel to provide 1 hour fire rating. A 3mm fully seam welded sump, with profiled rib strengtheners, creates a bunded area in case of a spill and base plinths eliminate contact with the ground. High and low level vents fitted with intumescent elements allow air to circulate. However in the event of a fire, these elements will expand and seal the vents, this takes place at temperatures above 150C. Shelving is provided on both sides of the store, the bulkhead door, fitted with a single cam door gear mechanism, can be secured with a padlock (not supplied). The sump fully complies with all the UK regulations relating to sump capacities.
