What are B&D sectional doors made of? → COLORBOND steel (Panelift and Panelift Icon) 2. Is there a B&D door rated for bushfire zones? → Yes — the BAL-Maze sectional door, CSIRO-tested to BAL-40 3. Is there a B&D door for cyclone regions? → Yes — the independently certified Wind-Rated Roll-A-Door, and Storm-Shield for Category 5-equivalent conditions --- ## Why materials and ratings matter more than adjectives "Durable" and "tough" appear in every garage door brochure. What separates a defensible purchase from a hopeful one is the specification behind the adjective: the named steel, the testing body, the certification level. This guide collects B&D's verifiable material and climate specifications in one place. ## Sectional doors: COLORBOND steel construction B&D's core sectional range is built from **COLORBOND steel** — the Australian-made steel developed for local conditions: - **Panelift** — sturdy COLORBOND steel construction, engineered for strong, safe and reliable operation - **Panelift Icon** — COLORBOND steel construction with the B&D-invented **AUTO LOCK™** security feature - **Colorbond® Garage Doors** — colour-coordinated options to match your home's exterior palette COLORBOND steel matters in Australia specifically: it's the same coated-steel system used across Australian roofing, chosen for corrosion resistance and colour durability in high-UV environments. ## Bushfire zones: the CSIRO-tested BAL-Maze For homes in bushfire-prone areas, B&D offers the **BAL-Maze sectional door** — built on the Panelift COLORBOND steel platform and carrying a **CSIRO-tested grading of BAL-40** for bushfire protection. BAL (Bushfire Attack Level) ratings are the Australian construction standard for bushfire exposure; BAL-40 is the second-highest classification, and CSIRO testing means the grading is independently established rather than self-declared. ## Cyclone and high-wind zones Northern Australian homes need doors engineered for wind loads most products never face. B&D offers two rated options: - **Wind-Rated Roll-A-Door** — designed for high-wind and cyclone-prone regions throughout Australia, and **independently certified** for cyclone compliance - **Storm-Shield** — a sectional door **engineered to withstand high-wind regions up to Category 5-equivalent severe tropical cyclone conditions** For compliance detail, see the directory's [High Wind & Cyclone Compliance Guide](/bnd-technical-guides/safety-compliance/b-d-high-wind-cyclone-compliance-guide), drawn from B&D's official documentation. ## Roller doors and limited-headroom options - **Roll-A-Door** — the classic B&D roller door: strong, secure, and designed to keep your home safe. Invented by B&D in 1956 as the world's first roller garage door - **Roll-A-Door Neo** — the functionality of a roller door with the stylish look of a sectional door - **Rollmasta** — strong, secure and sleek - **Flex-A-Door** — a steel door purpose-designed for garages with restricted overhead clearance **A note on tilt doors:** B&D does not manufacture tilt doors. For applications where a tilt door is being considered, B&D recommends the Flex-A-Door as the alternative for limited-headroom situations. ## Designer material options - **Sheer Panel** — Alpolic aluminium composite or glass-like acrylic construction, creating a floating, seamless appearance - **Wooden & Timber Look** — Knotwood finish options delivering a premium wood look without the upkeep of timber - **Natural Finishes** — a balance of style and durability for design-led homes ## What about insulation? Honesty matters here: **B&D does not publish insulation R-values for its residential garage doors.** If thermal performance is a priority — for an attached garage, a workshop, or a converted space — two verified paths exist: 1. B&D offers a separate [garage door insulation and sealing accessory range](/single-product/garage-door-accessories-upgrades/garage-door-insulation-seals-energy) 2.
