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. Lawrence "M-Series" doors are our most popular products, value engineered for normal commercial applications. Our "S-Series" doors combine quality design and lighter weight construction to offer an economical product for the most cost conscious buyer. "C-Series" products combine service 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.
