Metal Structure
Our metal structure workshop produces all key metal frame parts of MSDA chairs, including cantilever bases, structures, frames and supports for certain armrests. We use high-precision CNC equipment and OTC robotic welding to turn quality steel tubes into strong, dimensionally accurate chair frames.

Why Metal Structure Matters
The metal frame is the backbone of every chair. From the cantilever or the legs under the seat to the supports for the armrests armrest, it carries all weight, absorbs impact and determines how long the chair lasts.
At MSDA, we use thickened steel tubes and sometimes add inner sleeves at bending positions to reinforce the structure — designed in line with BIFMA 5.1 and EN 1335 standards. With OTC robotic welding and full-CNC processing, we produce uniform, strong and smooth metal frames with no weak weld joints. Every metal part passes strict load and impact tests to stay reliable for years of daily use.
At least 2.0mm Thickened Steel Tube OTC Robotic Welding BIFMA Standard Compliant 136kg Impact Test PassedFrom Tube to Finished Frame Processing Process
Every metal frame follows MSDA's standardized 9-step production process, from material cutting to final warehousing, ensuring consistent quality for every batch.
Quality Control
MSDA runs strict in-process inspection and finished product testing for all metal parts. We follow BIFMA standards and apply stricter internal quality rules.
136kg impact test for base and cantilever frames, 3 times of impact (vs. BIFMA 2 times) 136kg backrest strength test , 2 cycles with 1-minute hold 100% checked for even level of chair legs and cantilevers 100% visual inspection on weld seams and surface finish Full dimension sampling check for each batch Complete production records for full traceabilityFrequently Asked Questions
A: We mainly use 2.0mm and 2.5mm thick steel tubes. Bending positions of bow frames are reinforced with 2.0mm thick inner sleeves, designed per BIFMA load standards.
A: We use OTC brand robotic welding for mass production. It creates more even and smoother welds with less slag than manual welding, and keeps stable quality for every batch.
A: Finished metal parts are sent for professional surface processing, mainly powder coating and chroming. Custom colors and finishes can be supported per project requirements.
A: Yes. We support OEM/ODM customization for metal structures. With in-house CNC equipment and tooling capability, we can adjust tube size, bending shape and hole positions based on your design.
A: We use Taiwan imported CNC tube bending machines for one-step forming, with unified process parameters for each product model. We also conduct sampling dimension inspection for every batch to control tolerance.
A: All our metal frame structures are designed and tested in accordance with BIFMA X5.1 and EN 1335 standards. Test reports can be provided for your project tendering.
