Fire & Smoke Rated Doors
Since 1925, Lawrence Roll-Up Doors, Inc. has been manufacturing steel and aluminum rolling door products in Los Angeles, California. We offer various duty-cycle rated doors to meet the needs and budgets of each building owner or tenant. Our “H-Series” products are suitable for the most demanding conditions of heavy industrial settings, maximum-security environments, and high-frequency usage. Our “S-Series” fire doors combine quality design and lighter weight construction to offer an economical product for the most cost conscious buyer. “C-Series” products combine fire door features with more compact designs for service counters and other small openings. Decades of product design and manufacturing experience enable us to provide custom products to comply with special design and unique installation requirements.
Model HL Fire Doors combine many HD service door design features with simplified automatic closing and re-set functions to provide state-of-the-art fire protection for openings to 60′ wide, 50′ high, 1320 sq. ft.
Model SL Fire Doors offer the same closing and re-set systems of HL fire doors, but with a lighter weight door design intended for fire protection of smaller openings and less frequent usage. SL fire doors are suitable for openings to 14′ wide and 14′ high.
Model IL Insulated Fire Doors combine fire protection properties of HL fire doors with the benefits of thermal insulation and sound control for openings up to 44′ wide and 24′ high.
Model CL Counter Fire Doors provide the same high levels of fire protection and many of the same features as normal fire doors, but in a compact door design for smaller openings. Stainless steel trim & sill (counter top) are available. CL counter fire doors are limited in size to 16′ wide, 10′ high, 120 sq. ft.
Closing Systems – All “Easy-Reset” and “Auto-Reset” chain, crank and motor operated fire doors close automatically without a loss of spring tension and eliminate the need for traditional mechanical re-set. Interface with alarm systems/detectors and audible/visual warnings prior to closing are also available.
Retrofit Fire Door Operators – UL Labeled and FM Approved retrofit fire door operators are available for most types and brands of existing rolling fire doors. When retrofitted with these chain, crank or motor operators, even older fire doors can be tested and reset easily, operating with the same reliability and extraordinary descent control characteristic of our “Easy-Reset” and “Auto-Reset” fire door products.
