Heavy Engineering
Precision fabrication of high-strength steel joints and tapered portal frames designed to withstand cyclic fatigue in large-scale manufacturing plants. Every weld is 100% ultrasonically tested.
Heavy engineering for demanding environments
Automated welding process for thick-section steel joints. We control heat input and deposition rate to achieve full penetration with minimal distortion. Each weld is documented with a procedure qualification record.
Joint integrity verified by ultrasonic testingPhased-array and conventional UT for detecting internal flaws in welded connections. We scan 100% of critical joints in portal frames and crane girders. Reports include defect sizing and location mapping.
Compliance with AWS D1.1 and ISO 5817Tapered steel frames designed for overhead crane loads, thermal expansion, and cyclic fatigue. We use finite element analysis to optimize section geometry, reducing weight without sacrificing rigidity.
Tested for 10,000+ load cycles per specimenStraightforward answers about our heavy engineering services, from welding procedures to structural testing.
We focus on submerged arc welding for heavy structural steel, particularly for large-scale girders, portal frames, and industrial components. Our procedures are qualified for high-strength steels and thick sections common in mining, steel mills, and offshore platforms.
Every critical weld undergoes 100% ultrasonic testing to detect internal discontinuities. We also use visual inspection and, where specified, magnetic particle or dye penetrant testing. All inspectors are certified to relevant international standards.
Yes. We design and fabricate tapered steel portals optimized for overhead crane loads, thermal expansion, and cyclic fatigue. Each portal is analyzed using finite element methods to ensure stiffness and durability under real operating conditions.
Lead time depends on complexity and quantity. For a set of variable-section portals, expect 8 to 14 weeks from design approval to delivery. We provide a detailed schedule during the quotation phase and update it weekly throughout production.
Yes. We run cyclic load tests on representative weld specimens to validate fatigue life. Our lab can apply over 10,000 cycles per specimen while monitoring crack growth with acoustic sensors. Results are used to refine welding sequences and improve joint performance.
