Curtain Walls & Architectural Decoration

Curtain wall components include mullions, transoms, subframes, pressure plates and decorative caps. Other applications include edge-frame sections for canopies and railings, handrail tubes and base channels, facade grilles and louvers, louver blades and perimeter frames, suspended-ceiling slats, and interior skirting profiles. Components are selected to suit the project's architectural and installation details.

Typical requirements include straightness and twist in long mullions, mating clearances between frames and subframes or pressure plates and caps, visible-surface quality, color consistency across batches on the same facade, and mounting-hole accuracy. We check connections, interfaces and hole tolerances against the customer's curtain wall details and machining drawings. Customer-signed reference panels and first-piece trial assemblies are used to confirm finish color, coating thickness and cap fit before batch production.

Extruded components can be supplied in specified lengths or with agreed cutting, punching and further machining. Cut-to-length sawing and routine punching are performed in-house; specialist partners handle drilling, tapping and CNC machining. Our supply scope covers the agreed aluminum extrusions and processing. Perforated aluminum sheets, glass and steel structures shown in application photographs are outside this scope.

Provide complete profile cross-section drawings, curtain wall or decorative installation details, machining and hole-location drawings, and a bill of materials showing lengths and batch quantities. Specify the building's climate and exposure conditions, visible surfaces, required coating weather resistance, and any packaging or labeling by floor or installation zone. This information allows us to review mating interfaces, finishing processes and delivery arrangements.
