Profile System: We use a dedicated commercial door profile system that typically has a 45mm to 50mm face width and greater depth than residential, for strength. They often have double rebate (for double weather seals) and thicker walls for robust hinge and lock fixing. Stiles can be configured for various hardware (like wide stiles for panic bars or narrow stiles for maximum glass). The bottom rails can be low profile for ADA compliance or deep if you want a certain look or need to accommodate a floor closer. These systems come with anti-finger-trap stile options – where the hinge side stile is curved, leaving no pinch point when the door is nearly closed. All profiles are thermally broken for exterior use; interior use profiles might not have break if not needed.

Hardware & Accessories: Standard hardware on a swing door includes top and bottom pivots or heavy butt hinges (we often prefer pivots with an overhead closer in a transom for main doors – very durable and no hinges to sag; or a floor spring pivot for frameless look). We use quality closers – adjustable size EN 2-4 or 3-6 depending on door size. For locking: typically an Adams Rite hook lock (hook latch that goes into jamb strike) with an external euro cylinder – this is industry standard for storefronts. We can add a second lock or head shoot bolt for extra security. On double doors, flush bolts or tower bolts are used on the inactive leaf to secure it. For panic hardware: a crossbar panic device that opens the latch when pushed – we ensure they meet fire exit requirements and that frames have the proper strikes. We can fit door selectors (so the correct leaf closes first on double doors). Automatic options: we mount either a surface-mounted auto swing operator (with arms) or an integrated transom closer with motor – and can integrate safety sensors and push pads as needed. For sliding doors, we provide the whole automatic sliding unit (like Dorma or Geze system) integrated with our framing. Additionally, electro-magnetic locks can be installed (we usually put them at top rail, 600lb or 1200lb maglocks, with wiring hidden in frame). We also prepare for access control: if a card reader needs to be on mullion, we can cut out or provide mounting box etc. Door handles: commonly tubular pull handles (we supply 300mm, 1000mm D-handles, etc. in satin stainless steel or matching finish). If lever handles needed (less common on commercial main doors), we can provide those with appropriate heavy-duty locks. Also, kick plates of stainless steel ~200mm high can be applied to lower part if people push door with foot frequently. Weather wise: door sweeps or threshold drop seals can be installed to minimise drafts if needed, though commercial doors usually have a threshold with a seal built in.

Glazing: Usually glass for these doors is 6mm toughened or 6.4mm laminated if security is concern. For exterior, we normally do 24mm double glazing in the door too (with toughened outside, laminated inside for safety). The door profiles allow for glazing beads – typically externally beaded with security clip or internally beaded depending on design. All glass is safety glass by requirement for doors. If needed, we can do obscure glass, or incorporate a letterbox slot (commonly in bottom rail) if for a storefront that needs mail slot.

Thermal & Weather Performance: Our commercial doors (with thermal break) meet similar thermal values as windows – often around U=1.8 W/m²K for a glazed door with decent glass. They have wool pile or EPDM seals on all edges that compress to keep wind and rain out. We test them for water tightness (class up to maybe 4A, since doors not as tight as fixed frames, but still good for normal conditions) and air infiltration (they’ll meet required air tightness for building envelope). For extreme exposures, we can add second seals or specify more robust threshold solutions. The thresholds are typically low (about 15mm high) and thermally broken, achieving ADA compliance (1:2 slope edges). If greater water resistance needed, slightly higher threshold with a small ramp can be used.
-
Integration & Options: These doors integrate with our framing or existing openings. We can make them stand-alone too, with sub-frame if needed. They can open in or out (outward is common for egress). If an inward door needs to hold open, we can add hold-open closers or magnetic catches tied to fire alarm. For interior use, we may omit thermal break to save cost and if climate separation isn’t needed. We can do side lights or transom windows above doors using same profile system for a cohesive look. Also, if you need something like an overhead rolling shutter in same opening, we coordinate sizes or reinforcement. Special coatings: we can do anti-bacterial powder coat for hospital doors, or extra hardness coatings if heavy wear expected.
In sum, our aluminium commercial doors are feature-rich, designed to be the workhorses of a building, and we tailor all their components to your project’s specific functional needs while maintaining a uniform, clean appearance with the rest of the aluminium elements.
