Steel tube welding fabrication with certifications

Design: As per customer specific requirements
Or customer give us the specified sample;
Or the customer conceptual or preliminary design;
Or the customer sketched idea.
Accept drawing format: .jpg / .dwg / .igs / .stp etc..
Material: Sheet stock is of many materials, including
carbon steel, alloy steel, stainless steel, aluminum, brass even plastics.
Material condition: On flat sheet, plate coil supplying condition
Hot rolled or cold rolled or cold drawn for options.
Material thickness: From 0.2mm~6mm
Application material standard: If there is no any specially requirement, we often sugguest our customer to try the equivalent China National (GB) standard material that our engineering team proposes which to be properly converted from ANSI, ASTM, SAE, EN, DIN, BS, JIS, and etc., to contribute the material cost control.
If it is necessary to use exact designated material no., it is also possible choice.
Available processing (Technique):
- Shearing - Crimping - Laser cutting - Bending - Stamping - Pressing - Deep drawing - Rolling - Forming -

Fabricating - Drilling - Tapping - Riveting - Spot welding - TIG - Assembling

Precision: Average level: ±0.05mm, depending the part size and thickness and material

Tooling in house: To design and build the necessary tooling in own house, for the tooling we never add any margins, it just cost.

Blasting machines: 2 sets

Heat treatment (out house): For the heat treatment, we subcontract to our local qualified supplying factories to process at the out of Atlas house. Generally we can meet any heat treatment requirements on the metal works, such as annealing, normalizing, tempering & quenching, surface hardening and etc.
Surface treatment: The surface treatment is to do out house. Our suppliers help us to supply our customers a wide range of surface finish solution, such as hot dip galvanizing, zinc plating, nickel plating, chrome plating, powder coating, epoxy painting, anodizing, black oxide, E-coating and etc.
Inspection: Whole inspection procedures (IQC, PQC and FQC) and QA plan are carried out in house to be compliance with the rules and regulation of ISO 9001:200Quality control always be doing on site and on time, never try to do later;If the customer found it is necessary any third authorized inspection organization are welcomed to witness the quality before the shipment.
