Welding and Assembly Works and Manufacturing of Metal Structures in Dnipro — Ukrsteel Dnipro Steel Structure Plant

Welding is one of the most critical processes in metalworking and construction. The load-bearing capacity of the structure, its resistance to dynamic loads, and the safe operation of the entire industrial facility directly depend on the reliability of welded joints.

PJSC «Ukrsteel Dnipro Steel Structure Plant» offers industrial welding and assembly services of any complexity level. Our enterprise combines many years of experience (over 85 years in the market) with advanced European quality standards and strict control at every stage of production.

Regulatory Framework and Production Certification

The plant operates in accordance with the highest international and national quality standards for welding processes. This guarantees the legal and technical compliance of products with the strictest customer requirements:

• DSTU ISO 3834-1: an integrated welding quality management system has been implemented.
• DSTU EN ISO 9606-1 and 14732:2014: mandatory certification of each welder with confirmation of high qualification.
• DSTU B V.2.6-199 and DSTU B EN 1090-2: full compliance with the regulations for the manufacture of steel and aluminum structures.
• TÜV AUSTRIA Certificate: official confirmation of the plant's ability to perform welding work according to the EN 1090 standard with a high execution class up to EXC 4 inclusive (allowing the construction of bridges, high-rise structures, stadiums, and high-hazard facilities).

Technical Capabilities and Scale of Works

The production capacities of the plant allow assembling and welding elements with practically no limitations in complexity:

• Weight of structures: from individual complex assemblies to large-sized spatial sections weighing up to 50 tons.
• Component stages: upon completion of welding and assembly works, structures undergo mandatory preparation (shot blasting cleaning) and are sent for anti-corrosion protection in our own paint booth (26 × 6 meters).
• Types of products: frames of industrial buildings, hangars, warehouses, bridge crossings, masts, supports, trestles, and non-standard technological equipment.

Quality Control and Non-Destructive Testing (NDT) Methods

To eliminate any hidden defects (pores, cracks, incomplete fusion), a multi-level control system operates at the plant. All welds are subject to inspection using non-destructive testing (NDT) methods:

• Ultrasonic testing (UT): allows detecting internal metal and weld defects at great depth without destroying the structure itself.
• Magnetic particle testing (MT): an effective method for detecting surface and sub-surface cracks or incomplete fusion using a magnetic field and indicator powder.
• Visual and dimensional control (VT) at each assembly stage.

Why Entrust Welding Works to Ukrsteel Dnipro?

• Certified personnel: Our specialists hold international certificates, which makes it possible to work with high-strength and alloyed steels.
• Comprehensive approach: You receive a full cycle from preliminary metal cutting (laser or plasma), welding and assembly to shot blasting cleaning and final painting at a single plant.
• Industrial volumes: We ensure the execution of large-scale serial orders within clearly agreed deadlines.

Related Services and Production Capabilities

To implement construction and industrial projects of any complexity, PJSC «Ukrsteel Dnipro Steel Structure Plant» performs a full range of related works at its own production base:

• Laser sheet metal cutting — thickness up to 50 mm on a 2.5 × 12 meter worktable.
• Laser cutting of shaped rolled products, pipes and profiles — processing pipes up to 200 mm in diameter and up to 6 meters in length.
• Plasma cutting and drilling of beams — blanking of large-sized shaped rolled products up to 600×1800 mm.
• Shot blasting surface cleaning — metal preparation to Sa 2½ – Sa 3 degree for structures weighing up to 50 tons.
• Anti-corrosion painting of metal structures — protection systems according to ISO 12944 standards in a 26-meter-long booth.
