Aluminium Extrusion Profiles: Architectural Anodizing & Powder Coating
Evaluating billet heating, hydraulic extrusion presses, architectural anodizing tanks, electrostatic powder coating, and curtain walls.
Executive Overview & Strategic Context
Evaluating billet heating, hydraulic extrusion presses, architectural anodizing tanks, electrostatic powder coating, and curtain walls.
Contemporary architectural design in Bangladesh has transitioned from wood and steel window frames toward lightweight, corrosion-resistant aluminium fenestration. Domestic aluminium extrusion plants located in Gazipur, Narayanganj, and Chattogram melt imported primary ingots, extruding structural profiles for sliding doors, curtain walls, and industrial applications.
Market Structure, Capacity & Supply Chain Dynamics
Industry leaders (Chung Hua, KAI, Alumex, PHP Aluminium, BSRM Aluminium) operate hydraulic extrusion presses ranging from 1,200 to 2,500 tons capacity. Profiles are distributed through nationwide glass and hardware fabricator workshops.
Technological Drivers, Regulatory Landscape & Economics
Manufacturing uses 6063-alloy aluminium billets heated to 450°C-480°C and forced through hardened H13 steel dies. Profiles undergo water-quench cooling, automated stretching, and aging in precipitation-hardening ovens (T6 temper). Surface finishing employs vertical powder-coating booths or computerized architectural anodizing baths.
Comparative Benchmarks & Operational Metrics
| Surface Treatment | Coating Thickness | Hardness / Adhesion | Salt Spray Resistance | Architectural Application |
|---|---|---|---|---|
| Silver Matt Anodizing | 15 - 20 Microns | 300 - 350 HV (Oxide) | 1,000 Hours (ASTM B117) | Residential Sliding Windows |
| Bronze / Champagne Anodized | 20 - 25 Microns | 350 HV (Electrolytic Color) | 1,500 Hours | Commercial Storefronts & Partitions |
| Architectural Powder Coat | 60 - 80 Microns | 2H Pencil Hardness | 2,000 Hours (UV Protected) | Modern High-Rise Exterior Facades |
| Thermal-Break Profile | Insulated Polyamide Strip | Structural Thermal Barrier | Complete Condensation Stop | Energy-Efficient Green Buildings |
Strategic Industry Outlook & Investment Projections
Surging construction of LEED-certified green industrial factories and commercial office towers is expanding demand for thermal-break insulated profiles that minimize interior air conditioning heat loss.
Interactive Expert Q&A Drawer
How much aluminium extrusion does Bangladesh consume annually?
National consumption exceeds 85,000 to 100,000 metric tons annually, driven by commercial curtain-wall facades, sliding windows, and industrial structural profiles.
What is the difference between anodized and powder-coated aluminium profiles?
Anodizing electrochemically thickens the natural aluminum oxide layer (15-25µm) creating a metallic finish, whereas powder coating electrostatically sprays cured polymer resin providing unlimited colors and UV protection.
