Overview
MIL-SPEC Heavy Steel Fabrication Services
Dengtai specializes in heavy steel fabrication for defense and military applications. Our 50,000 m² facility is equipped with CNC plasma cutters handling plate up to 150 mm thick, 100-ton overhead cranes, and robotic welding stations certified to AWS D1.1 and ISO 3834 standards. We fabricate armor components, structural hull sections, turret inserts, and ballistic shielding for armored vehicles, naval vessels, and fixed fortifications.
Every defense project follows a strict quality management system compliant with ISO 9001:2015. Our NDT lab performs ultrasonic testing (UT), magnetic particle inspection (MPI), and radiographic testing (RT) on all load-bearing welds. We maintain full material traceability from mill certificate to final assembly, with documentation packages meeting MIL-STD-129 and DFARs requirements.
From prototype development to full-rate production, Dengtai delivers heavy steel defense components with tight tolerances and on-time delivery. Our engineering team works directly with your design staff to optimize fabrication drawings for manufacturability, reducing lead times while maintaining ballistic integrity and structural performance.

Features
Features & Benefits
MIL-SPEC Certified Welding
All welding procedures are certified to AWS D1.1 and ISO 3834-2. Our WPS/PQR database covers over 200 material combinations for armor and structural steel grades.
Full Material Traceability
Every plate and consumable is tracked from mill certificate through fabrication to final dispatch, with complete documentation packages meeting MIL-STD-129 and DFARs requirements.
Multi-Axis CNC Machining
5-axis CNC machining centers handle complex geometries on armor-grade steel with tolerances of ±0.5 mm, eliminating secondary operations.
In-House NDT Laboratory
On-site NDT lab performs ultrasonic, magnetic particle, radiographic, and dye penetrant inspection, certified to ASNT SNT-TC-1A.
Large-Scale Capacity
50,000 m² facility with 100-ton overhead cranes and 12 m x 4 m x 3 m working envelope handles the largest defense fabrications.
Rapid Prototyping
Dedicated prototype cell with rapid tooling changeover enables first-article fabrication in as little as 2 weeks for urgent defense programs.
