As a fully integrated high-tech aluminum enterprise established in 1998, CHAL Aluminium Corporation operates a complete industrial chain covering billet casting, extrusion, cold drawing, HF welding, composite cladding and finished tube machining, manufacturing six core aluminum tube products: drawn aluminum tube, aluminum welded tube, seamless aluminum tube, extruded aluminum tube, composite aluminum tube and aluminum condenser header pipe. This article analyzes CHAL’s production layout, capacity distribution and end-to-end customized service system supporting automotive, HVAC, solar and precision equipment global clients across 13+ countries including Southeast Asia, the Middle East and North America.
CHAL’s upstream self-owned aluminum billet casting workshops guarantee raw material quality control, testing chemical composition for every batch to eliminate impurities that cause tube cracking during drawing or welding. Midstream production facilities are divided into specialized workshops matching each tube category: The extrusion workshop equips 1650T–3600T extruders to produce extruded aluminum tube and seamless tube blanks in round, square, rectangular and flat oval cross-sections. The cold drawing workshop operates dedicated lines for drawn aluminum tube, capable of manufacturing internal grooved tubes, capillaries and peanut tubes with annual output of 10,000 tons, implementing zinc spray anti-corrosion and degreasing finishing processes. The high-frequency welding workshop features six professional lines for aluminum welded tube, with 15,000 tons yearly capacity of radiator flat tubes, intercooler turbulator tubes and multi-port microchannel profiles. The composite cladding workshop produces bi-metal composite aluminum tube and finished aluminum condenser header pipe, including pre-punched manifold products for automotive OEMs.
Capacity allocation reflects market demand focus: Drawn aluminum tube production prioritizes HVAC evaporator raw materials with 5,000 tons smooth round tube and 3,000 tons internal grooved tube annual output. Aluminum welded tube lines concentrate on automotive radiator and intercooler supply, while composite tube and condenser header pipe workshops deliver 2,500 tons of cladding header tubes annually for global auto brands Mahle, Denso, Midea and Panasonic. All production equipment imports German casting machines, UK zinc metallization systems and Japan/Korea fixed-length cutting machines to maintain consistent dimensional precision meeting ASTM, AMS and automotive TS16949 standards.
CHAL’s standardized order process unifies all six tube product categories, following a clear workflow: customer inquiry submission → feasibility study & quotation → customer order confirmation → PI signing → deposit receipt → mold design & sample trial → sample approval → mass production → balance payment → final delivery. The customized service system covers full technical support, including customer-specific alloy formulation, temper adjustment (O, T4, T5, T6, H series), tolerance customization, coil winding, fixed-length cutting, CNC bending and surface treatments such as anodizing and flux coating. For aluminum condenser header pipe clients, CHAL offers one-stop stamping service to process fluid distribution slots, eliminating secondary machining costs for downstream heat exchanger manufacturers.
Quality control runs through every production stage: raw billet chemical inspection, online eddy current testing for welded tube seam integrity, burst pressure testing for seamless and composite tubes, salt spray corrosion testing for zinc-sprayed drawn aluminum tube and dimensional tolerance full inspection before packaging. Finished tubes are packed with plastic film and fumigated wooden pallets suitable for ocean transportation, shipped from Shanghai and Qingdao ports with flexible T/T and L/C payment terms.
For global buyers sourcing heat exchange aluminum tubes, CHAL’s full industrial chain integration delivers factory-direct pricing, stable delivery cycles within 15 days and technical simulation support for new product development, covering all core tube types from basic extruded profiles to high-end composite aluminum condenser header pipe and precision drawn aluminum tube for diverse industrial cooling applications.
