Client Testimonials

"The rotary kiln is a key part of the process flow sheet at Araguaia. The 11 individual sections of the kiln will now be welded together over the course of the next month, before the sections are lifted into place on top of the kiln piers for final welding and alignment. We wish to extend our thanks to everyone involved in the massive logistics process required to deliver the kiln to site."
Mr. Walter | CFO, FLD
"Under the condition of high technical requirements, difficult production and tight delivery time, Openex Metal Fab completed the processing of products on time and with high quality, which ensured the construction progress of our oil project.

Frequently Asked Questions

Custom Metal Fabrication: Buyer Questions

Practical information to help engineering and procurement teams prepare a manufacturing inquiry.

What types of custom metal fabrication does Openex provide?
Openex provides custom metal fabrication and manufacturing services for industrial components and assemblies. Depending on the project, the scope can include material preparation, cutting, forming, welding, machining, finishing, assembly and inspection.
Can Openex handle large and heavy industrial components?
Openex operates a large manufacturing facility with a stated site area of 180 acres and 55 lifting cranes with capacities ranging from 3 to 250 tons. Actual project feasibility depends on component dimensions, weight, lifting arrangements, manufacturing route and the equipment required.
Can fabrication and CNC machining be managed by one supplier?
Yes. Where the project and equipment requirements are suitable, fabrication and CNC machining can be coordinated within the same manufacturing operation. This can simplify production planning, dimensional control and handoffs between suppliers.
Which materials can Openex work with?
The materials listed on this page include carbon steel, stainless steel, alloy steel, aluminum, heat-resistant steel and duplex or super duplex stainless steel. Final material availability and suitability should be confirmed against the project specification.
What information should I provide to request a quotation?
Provide the component drawings or 3D models, material grade, quantity, overall dimensions, critical tolerances, applicable standards, inspection requirements, surface treatment, delivery location and requested delivery date. If some details are not finalized, send the available information for an initial review.
Can Openex support inspection and project quality documentation?
Inspection requirements can be discussed during quotation, including dimensional verification and applicable non-destructive testing. Required inspection methods, acceptance criteria, certificates and documentation should be agreed before production.
