OVERVIEW

Engineered for High-Traffic Durability & Security

Steel remains the undisputed industry standard for residential garages requiring exceptional security, structural stiffness, and low maintenance. Heavy-gauge galvanized steel skins protect against accidental vehicle nudges, flying gravel, and harsh seasonal ice and salt exposure.

Our steel door installations pair multi-layer hot-dip zinc coatings with polyurethane insulated core sandwich construction. This creates an extremely rigid, wind-resistant door panel that will not warp, sag, or flex across wide multi-car doorways.

SPECIFICATIONS

Steel Construction & Structural Profiles

Hot-Dip Galvanized Zinc Layer

Multi-stage corrosion protection prevents rust formation on interior and exterior steel surfaces even in coastal Finnish zones.

Micro-Ribbed & Flush Profiles

Horizontal micro-groove patterns and mid-rib contours that increase sheet rigidity and produce crisp architectural shadow lines.

Heavy-Gauge Steel Hinges

14-gauge structural steel intermediate and end hinges engineered to bear dynamic continuous cycle loads without ovaling.

Baked Polyester Enamel Topcoat

Factory-cured finishes resistant to UV chalking, scratches, and road grime, requiring only simple annual water washing.

SCOPE OF WORK

What’s Included in Steel Door Installation

  • Structural Opening Evaluation: Assessing lintel bearing strength, masonry anchor points, and doorway squareness.
  • Heavy Steel Section Assembly: Stacking galvanized steel panels with high-density polyurethane core insulation.
  • Rigid Commercial-Grade Brackets: Mounting heavy-duty bottom brackets, adjustable top fixtures, and track angle supports.
  • High-Cycle Counterbalancing: Setting oil-tempered torsion springs calibrated to the exact weight of the steel panel package.
  • Perimeter Thermal Sealing: Installing 4-sided weather seals to eliminate wind noise and drafts around the steel framework.
QUESTIONS & ANSWERS

Steel Door FAQs

No. Our steel garage doors feature multi-tier protection: hot-dip zinc galvanizing, an epoxy primer base, and a baked polyester powder coat that completely seals the raw steel against road salt, snow, and rain.

Our residential doors utilize 24 to 26-gauge steel skins backed by 40mm to 45mm of high-density injected polyurethane foam. This sandwich construction delivers structural rigidity equivalent to much heavier solid steel plates without excessive motor strain.

Steel doors require very little maintenance. An annual wash with mild detergent and water, coupled with a light silicone spray on the steel hinges and roller bearings, keeps the system operating flawlessly for decades.
