Why Lonsonstrut Brackets Outperform Conventional Steel
Through continuous material R&D and over 100 patents, our proprietary high-strength aluminum alloy support system eliminates the structural weak points and corrosion penalties of welded steel.
Tensile Strength Up to 728 MPa
Yield strength reaching 604 MPa gives our engineered aluminum brackets higher specific strength than Q235 steel at 1/3 the structural weight.
Integrated Extrusion & Stamping
No heat-affected weld zones. Integrated forming eliminates weld cracking, rivet looseness, and localized bending stress concentrations.
Non-Ferromagnetic Eddy Protection
Prevents inductive heating and energy losses in close proximity to massive AC power conduits and high-current data center switchgear.

Frequently Asked Questions
Answers to common technical, material, and procurement questions for engineering contractors, distributors, and MEP system installers.
Are Lonsonstrut brackets compatible with standard 41mm channels from other brands?
Yes. All Lonsonstrut angle brackets, cantilever arms, base plates, and spring nuts adhere strictly to international 41mm strut framing modular geometry (including 41×21mm, 41×41mm, 41×62mm, and 41×82mm profiles with 22mm slot widths and 14mm hole patterns).
How does high-strength aluminum alloy compare to hot-dip galvanized steel?
Our proprietary aluminum alloys achieve tensile strengths up to 728 MPa and yield strengths up to 604 MPa—exceeding Q235 steel while weighing roughly one-third as much. In addition, aluminum forms a natural self-healing oxide layer that prevents corrosion in humid underground tunnels and coastal air without flaking or rust bleeding.
Why is non-ferromagnetic material critical in power cable support?
When high-voltage AC current passes through single-core cables, conventional steel support frames form closed magnetic loops that generate inductive eddy currents. This causes significant parasitic heating, energy loss, and accelerated corrosion. Non-ferromagnetic aluminum clamps and brackets eliminate eddy current induction entirely.
What quality documentation and testing reports do you provide?
We provide EN 10204 3.1 Mill Test Certificates, tensile/shear test reports, salt spray corrosion test data (500 to 1,000+ hours), coating thickness verification, and 2-million-cycle fatigue test reports for concrete insert channel systems upon request.
How do your connection accessories achieve high slip resistance?
Our brackets and channel accessories incorporate engineered 3D wedge geometries, serrated channel nut surfaces, and precision mechanical interlocks. According to lab test data, these anti-loosening connection designs deliver an approximate 83% improvement in slip resistance under continuous dynamic vibration.
How do concrete insert channels eliminate structural post-drilling risks?
Pre-cast embedded concrete insert channels eliminate the need for post-installed expansion anchors. This prevents damage to internal reinforcement rebar, eliminates concrete micro-cracking, reduces overhead hot work on site, and has completed over 2 million fatigue cycles for subway and rail transit applications.
Can you manufacture custom brackets and OEM accessories from drawings?
Yes. With in-house tooling, high-precision stamping, robotic welding, and progressive die engineering, Lonsonstrut supports OEM/ODM production per your CAD/BIM drawings. Custom hole patterns, non-standard bending angles, special thicknesses, and customer-branded markings are fully supported.
What are the typical lead times and export packaging standards?
Standard catalog items ship in 7 to 15 business days, while custom OEM runs average 14 to 25 days after sample approval. All hardware is packed in heavy-duty reinforced cartons, palletized on heat-treated fumigated wooden pallets, and wrapped in moisture-resistant film for long-distance sea container transport.
