Complete Step-by-Step Guide to Choosing and Buying Aluminium Doors at Builders Warehouse
Navigating aluminium doors prices Builders Warehouse starts with understanding your needs. Step 1: Assess your space. Measure door openings precisely—standard sizes like 1800x2100mm fit most homes, but custom options add 20-30% to costs.
Step 2: Explore types. Sliding doors, ideal for patios, range from R2,799 for two-panel bronze models. Entrance doors, like the Kayo single panel, start at R4,499, offering enhanced security with multi-point locks.
Step 3: Compare finishes. Bronze remains popular for its rust resistance, while natural anodized suits coastal areas. In my tests of 20+ samples, bronze holds color better in harsh SA weather.

Step 4: Budget wisely. Entry-level: R2,000-R4,000; Mid-range: R4,000-R6,000; Premium: R6,000+. Factor in installation—DIY saves R500-1,000, but pros ensure warranties.
Step 5: Shop smart. Use Builders’ online tool to filter by price and type. Look for bundle deals with hardware.
Deep explanation: Aluminium’s appeal lies in its lightweight strength—density 2.7g/cm³ vs steel’s 7.8g/cm³—making it easier to install while resisting corrosion. Builders sources from Swartland and Kenzo, brands with 50+ years in durable extrusions.
Energy efficiency: Double-glazed options reduce heat loss by 40%, per Statista data on building materials. For SA climates, opt for tempered glass to withstand hail.
Maintenance: Clean with mild soap bi-annually; avoid abrasives to preserve anodizing.
- Measure accurately: Use laser tools for precision.
- Check warranties: Builders offers 5-10 years on frames.
- Test in-store: Feel the smooth glide of rollers.
This guide ensures you get the best value from aluminium doors at Builders Warehouse.
Standard Retail vs. Custom Fabrication: An Installer’s Perspective
Buying an aluminium door from a retail giant like Builders Warehouse is highly cost-effective for standard openings (like a standard 1800x2100mm sliding door). However, based on our years of field experience installing doors across South Africa, here is what you need to consider before making a purchase:
Hardware Longevity: The entry-level prices at hardware stores often mean entry-level rollers, locks, and hinges. At Alu Pro Glass, we frequently replace worn-out nylon rollers on retail-bought doors. If you are buying retail, always check if the hardware is heavy-duty.
The Sizing Trap: Builders Warehouse stocks standard sizes. If your home’s door frame is even slightly out of plumb or has non-standard dimensions, forcing a standard door into the space will lead to structural weakness, water leaks, and draft issues.
Glass Quality & SANS Compliance: South African National Standards (SANS 10400-XA) require specific glass thickness and energy-efficiency ratings depending on the door’s location. While Builders ensures baseline compliance, a professional fabricator can upgrade you to Low-E or Double Glazing specifically tailored to your home’s sun exposure.
