Commercial Doors and Hardware Suppliers

Commercial-grade doors are built to withstand high traffic, security demands, and strict building codes. Key attributes include heavy-duty steel construction ranging from 18 gauge to 12 gauge, specialized internal cores like polystyrene, polyurethane, or steel stiffeners, reinforced hardware anchoring, and certified compliance with standards such as UL fire ratings and NAAMM specifications.

A commercial grade door is a heavy-duty opening assembly engineered for commercial, healthcare, or institutional buildings. Unlike residential doors, these doors utilize durable materials like galvannealed or stainless steel, welded or knock-down frames, and specialized cores. They frequently incorporate UL-labeled fire-rated protection, double egress functions, or radiation shielding to ensure safety and structural longevity.

Custom Metal Products offers multiple core configurations for custom hollow metal doors. Options include polystyrene, polyurethane, temperature rise, and steel-stiffened cores. These core types allow builders and distributors to address specific insulation, thermal performance, sound dampening, structural stiffness, and fire-rating requirements across diverse commercial building installations.

Commercial doors are available in steel thicknesses ranging from 18 gauge to 12 gauge, utilizing A60 galvannealed or stainless steel. Hollow metal door frames, engineered sidelite and transom assemblies, and lead-lined frames are offered in steel thicknesses from 16 gauge to 12 gauge to accommodate standard and heavy-duty structural requirements.

Doors and frames can be manufactured with UL fire-rated labels meeting NAAMM and HMMA standards. Options include flush or embossed steel doors, temperature rise core assemblies, double egress frame assemblies, and fire-rated sidelite, transom, and borrowed light frame installations designed to satisfy commercial egress and life-safety building codes.

Standard lead times are seven to ten business days for doors and five to seven business days for frames. In addition, quick-ship programs are available with turnaround times of one, two, three, or five business days, with select products and configurations eligible for same-day dispatch.
