Socket aluminum profiles are sturdy, lightweight aluminum bars made with built-in channel “sockets” along their length, designed for easy, tool-friendly assembly. Unlike standard aluminum parts, these profiles let you slide connectors, brackets, or panels directly into the built-in slots without complex welding or drilling. They are lightweight yet strong, resist rust and wear, and stay smooth and stable indoors or outdoors.
Their socket-style channels make assembly fast and flexible: you can adjust, extend, or rebuild frames, racks, enclosures, or mounting structures anytime. They work for home setups, office fixtures, equipment frames, and retail displays alike. Easy to cut to size and compatible with standard fasteners, socket aluminum profiles blend practicality, durability, and clean looks. They simplify building stable, professional structures without specialized skills, offering long-lasting use with little maintenance.

High structural strength and rigidity:Aluminum alloy ensures stable load-bearing performance, reducing deformation under stress.
Lightweight material: Lower density than steel, making transportation, installation, and handling more efficient.
Excellent corrosion resistance:Natural oxide layer and surface treatments resist rust and oxidation, suitable for humid or outdoor environments.
Precise socket connection: Standardized slot and plug design enables stable assembly, easy disassembly, and reconfiguration without complex tools.
Good processability: Supports cutting, drilling, bending, and surface treatment (anodizing, spraying), adapting to diverse structural needs.
Heat dissipation and electrical conductivity:Effective thermal emission and safe electrical performance for industrial and electrical applications.
Eco-friendly and recyclable: Aluminum is highly recyclable with low energy consumption for reprocessing, meeting sustainable production requirements.
Sizes follow metric modular series:20×20, 30×30, 40×40, 45×45, 60×60 mm, plus rectangular variants (20×40, 30×60, 40×80 mm). These define profile width/height and match fasteners, brackets, and accessories.
Standard socket (T‑slot) widths: 6 mm, 8 mm, 10 mm. Slot depth typically 8–12 mm to ensure stable bolt/slider locking. Slot design directly determines load capacity and assembly flexibility.
Wall Thickness: Usually 1.5–3 mm, balancing light weight and rigidity. Thicker walls boost strength for heavy‑duty frames; thinner versions suit lightweight setups.
Common stock lengths:3 m, 6 m, with tight tolerance (±0.2 mm). Custom cut lengths are widely available for on‑site fitting.
Structural & Functional Sizing: Includes corner radius, inner bore holes (for threading M6/M8/M10), and slot spacing. These ensure compatibility, stability, and ease of machining.
Purpose & Matching: Dimensions are standardized globally for interchangeability. Small profiles (20/30 series) for light frames; medium/large (40/60 series) for industrial workstations, guards, and automation structures.
Basic classic colors: Silver brushed, matte black, champagne gold, pure white, light gray. These colors are versatile, resistant to dirt, and fit most building styles.
Customized color options: RAL color system matching, wood grain transfer printing, marble texture simulation, and metallic luster tuning. It can be tailored to building interior design requirements.
Special scenario matching colors: Hospital - soft beige, light blue (soothing and clean); Commercial building - bright rose gold, titanium gray (high - end and modern); Residential building - warm cream, light wood color (comfortable and homelike).

Established in 1985, Huzhou Yindu Aluminium Co., Ltd.(formerly called 721 factory of Huzhou)is a professional manufacturer of aluminium profiles. It was converted to Huzhou Yindu Aluminum Co., Ltd., and moved to Yanghua Village Zone, Nanxun Town, with a new name of Huzhou Yindu Aluminum Science and Technology Company, located in the ancient town of Nanxun, Huzhou, Zhejiang Province.
Our company is a local large-scale enterprise with more than 120million yuan in capital assets,42,000 square meters of covering area, and up to 10,000 tons of annual production capacity of aluminium profiles. We are awarded as“Key Enterprise of Huzhou, Zhejiang”, “Council of Huzhou Metallurgy Chamber of Commerce”, “AA–Credibility Enterprise of Industry&Commerce in Zhejiang Province”, and“Huzhou Credibility Enterprise”.
With over 30 years of hard work and continuous development, we already have advanced equipment and scientific management. Presently, there are many workshops, including aluminium extrusion, mechanical polishing, oxidizing staining, electrophoretic painting, powder electrostatic painting, water spray paint, doors and windows making, machinery processing, etc., as well as a quality monitoring center, which formed a complete modernized production scale of aluminium profile.
We can produce various aluminium alloy building and decorative materials according to customers’requirements; aluminium alloy tubes, rods, profiles used in industry, agriculture, vehicles, and ships. The anode oxidation and electrophoresis of aluminium alloy can produce different types of colors, such as black,bronze-colored, champagne color, imitate stainless steel color, silver-white rub sand, ordinary silvery white, hard oxidation, etc. Powder electrostatic painting can produce various tinted green aluminium profiles. The company also produces building tempered glass, escalator tempered glass, shower room tempered glass, etc.
We are permitted by the national industrial products and have registered “Yindu” as our trademark. Additionally, we have been named as“Famous Trademark of Huzhou” and“Famous Brand of Huzhou”.We have passed ISO9001 International Quality System, ISO 14001 environmental management system, ISO 45001 safety management system, and IATF 16949 quality management system. We are awarded as the“Civilized unit of Nanxun, Huzhou City”, “Star Enterprise”, “Leader for Tax Payment”, and other honors.
Our“Yindu” products are well sold to Jiangsu, Zhejiang, Shanghai, Anhui, Shandong, Liaoning, Heilongjiang, Jilin, and other big and medium-sized cities, and some have been exported to Japan, Australia, France, Switzerland, Europe, and the United States. Quality for Credibility; Credibility for Market; Market for Reform; and Reform for Development”—This is our guide principle. Credibility is our Guarantee, Quality is our Root, and Service is our Tenet. We strive to provide reliable services for our customers with quality products, a wide variety, and reasonable prices. We hope that the “Yindu” aluminium alloy profile will become your preferred choice.
