View Product DetailsThe 35 x 70 mm aluminum extrusion profile is an intermediate, high-performance structural element designed to bridge the gap between light-duty profiles (such as 30 x 30 or 40 x 40) and extremely heavy structural frames (like 80 x 80 or 100 x 100). The unique geometry of a 35 x 70 mm cross-section offers an optimized weight-to-strength ratio, saving material volume and project weight while delivering exceptional torsional resistance along its major axis.
Globally, industrial automation, modern cleanrooms, and linear motion configurations demand frame systems that can handle significant bending moments without occupying excessive space. The 35 x 70 structural section is highly favored in European and American automated manufacturing cells because it aligns perfectly with both modular grid alignments and ergonomic heights for workstation support legs.
"Precision engineering dictates that saving weight without sacrificing safety margins is the ultimate efficiency. The 35 x 70 profile design provides the exact localized rigidity required for high-stress automated framing."
Chengdu E&I Aluminum Industry Co., Ltd. is a premier manufacturer specializing in high-difficulty, high-precision, and high-specification aluminum alloy products. Aligned with the business philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation," the company provides fully integrated extrusion, anodizing, powder coating, and structural assembly services.
Leveraging deep technical partnerships with the National Institute of Nonferrous Metals, Chengdu E&I operates with a professional aluminum alloy technology research and development team at the forefront of China's light alloy industry. This technical backing allows the company to supply custom overall solutions across profiles, castings, and forgings, serving top-tier international businesses, including automotive manufacturers and aerospace giants.
By enforcing rigorous inspection standards, utilizing advanced CNC machining centers, and controlling the extrusion process from melt to finish, Chengdu E&I creates value-for-money commercial partnerships, earning widespread acclaim across international industrial sectors.
From custom profile designs, mold manufacturing, and automated extrusion lines to secondary processing (drilling, tapping, milling) and surface finishes, Chengdu E&I delivers complete modular solutions. Our products power industrial frames, cleanroom enclosures, solar brackets, conveyor tracks, and storage systems worldwide.
We primarily utilize AA6063-T5/T6 and AA6061-T6 aluminum alloys. AA6063 offers superior surface finishes, while AA6061 provides high tensile strengths (up to 290 MPa) for structural frameworks subjected to cyclic dynamic loads.
Engineered with standardized slot dimensions (8mm or 10mm slot widths), the profiles allow seamless connection with standard T-nuts, brackets, and custom accessories, ensuring quick assembly and rigid joints.
Produced under high-precision requirements, our extrusions strictly limit straightness deviation to ≤0.1mm per meter. The surface anodizing layer thickness ranges from 10μm to 25μm, delivering high corrosion resistance.
China's aluminum profile factories have transitioned from basic material suppliers to leaders in high-value, precision engineering. Supported by integrated industrial clusters and advanced raw material supply chains, Chinese manufacturers offer unique advantages:
Used to construct heavy-duty robotic framing, machine guards, assembly lines, linear guide supports, and material shuttle units requiring stable structural frames.
Excellent for structural legs, conveyor tracks, and crossbeams. Our profiles handle high dynamic loads and resist constant vibration without loosening.
Ideal for drawer-type workbenches, laboratory desks, and ESD-safe cleanroom stations. Simple T-slot integration supports easy additions of shelves, lights, and tool organizers.
To rank among the top three in China's aluminum alloy industry for innovation and competitiveness, delivering superior products and fostering shared growth with our clients and partners.
We value our employees as our greatest asset, offering competitive compensation and clear paths for professional development and shared success.
We deliver high-performing products and reliable customer support, ensuring consistent structural integrity and commercial value for our partners.
We continuously invest in R&D to drive product, process, and management innovations, ensuring our structural profiles remain at the forefront of the industry.
Win-Win Cooperation: We collaborate closely with clients, employees, and stakeholders to build long-term, mutually beneficial strategic partnerships.
When sourcing 35 x 70 mm structural aluminum profiles internationally, buyers should define key technical specifications to ensure quality and compatibility:
Procurement Checklist: Verify mechanical properties, including Yield Strength (Rp0.2), Tensile Strength (Rm), and Elongation (A50mm) via certified mill test reports before shipment.
The 35 x 70 mm profile offers a more compact footprint, making it ideal for systems with limited space. It reduces weight by roughly 12% to 18% compared to a 40 x 80 mm profile of the same wall thickness, helping lower material costs and load requirements while retaining high bending resistance along its 70mm axis.
The standard alloy is AA6063-T5, chosen for its excellent surface finish and adaptability to anodizing. For higher stress demands, AA6061-T6 is available, providing greater yield strength (minimum 240 MPa) and improved performance under static and dynamic loading.
We maintain straightness within ≤0.1mm per meter by using specialized tension-straightening machinery post-extrusion. Cross-sectional dimensions are monitored via automated digital calipers and optical comparators to ensure compliance with high-precision international standards.
Yes, our profiles are designed with standard 8mm and 10mm slot widths. This guarantees full compatibility with standard metric fasteners, including roll-in T-nuts, angle brackets, and cross-connectors, simplifying integration into existing modular assemblies.
