The Bilco Co.

What The Bilco Co. does

The Bilco Company designs and manufactures specialty access solutions for the commercial and residential construction markets. Its product portfolio spans roof hatches, floor access doors, automatic smoke vents, fire-rated floor doors, flood-tight doors, basement doors, egress window wells, fall protection grating, telescoping safety posts, and intruder defense systems. Engineering emphasis is on lift assistance mechanisms, corrosion-resistant materials (aluminum and Type 316 stainless steel), and compliance with OSHA fall protection, NFPA fire rating, UL smoke vent, and IRC egress code requirements, with multiple granted U.S. utility patents protecting core product families. The company operates four manufacturing sites in Connecticut, Arkansas, Ohio, and Juarez, Mexico, and employs approximately 300 people.

BILCO serves two primary customer segments. Commercial customers include architects, engineers, specifiers, and construction trades specifying access, fire safety, and fall protection products for factories, warehouses, transit systems, and public buildings. Residential customers include homeowners, custom home builders, and remodelers purchasing basement doors, egress window wells, and PermEntry precast basement entrances through dealers and national home centers. The company runs dedicated Independent Installer and Model Home Programs offering co-op funding, job referrals, product rebates, and marketing support to participating contractors.

Revenue is generated through one-time hardware sales via a dealer and sales representative network covering all U.S. states and Canadian provinces, with national home center distribution and online accessory sales supplementing the residential channel. No public pricing is listed, and revenue figures are not disclosed. BILCO was founded in 1926 by George W. Lyons, acquired by Quanex in 2024, and operates today as part of the Quanex Access Solutions Division. The company is celebrating its 100th anniversary in 2026.
