Shot Blasting Metal Surface Cleaning in Dnipro — Ukrsteel Dnipro Steel Structure Plant
High-quality surface preparation of rolled steel and finished welded structures is the foundation upon which the durability and reliability of all anti-corrosion protection directly depend. Even the most expensive and highest-quality paint system will prematurely begin to peel off if traces of rust, scale, grease, or micro-oxides remain on the metal.
PJSC «Ukrsteel Dnipro Steel Structure Plant» offers industrial shot blasting metal cleaning services on a powerful modern line. We perform thorough surface preparation both for the plant's own needs and upon orders from third-party enterprises, guaranteeing strict compliance with international quality standards.
Technical Capabilities and Cleaning Standards
Our enterprise is equipped with high-performance machinery that allows processing both individual elements (sheets, profiles, pipes) and massive large-sized structures:
- Surface cleaning degree: Sa 2½ – Sa 3 in accordance with the international standard ISO 8501. This means the complete removal of rust, old coatings, scale, and foreign inclusions down to obtaining a uniform matte metallic shine.
- Roughness control: Rz ≥ 40 µm according to the ISO 8503 standard. Optimum roughness creates the necessary "micro-profile" ("anchor effect"), ensuring maximum adhesion (bonding) of liquid primers and paints to the metal surface.
- Dimensions and weight of products: The shot blasting chamber allows accepting structures weighing up to 50 tons with maximum dimensions of 24 × 3.6 × 3.6 meters for processing. This makes it possible to clean not just parts, but also solid large-sized welded assemblies, trusses, columns, and sections of metal structures.
Why is Shot Blasting Cleaning Critically Important for Your Project?
Many mistakenly perceive metal cleaning as a formal or secondary procedure. However, engineering practice proves otherwise:
- Prevention of sub-film corrosion: If even microscopic scale or traces of rust remain under the paint layer, the metal oxidation process will continue inside under the influence of moisture. Over time, this will lead to blistering and peeling of the coating.
- Maximum paint adhesion: Shot blasting treatment with steel shot does not just "wash" the metal, but forms a rough surface at the micro-level. The contact area between the metal and paint increases manifold, guaranteeing strong retention of the protective layer for decades.
- Relief of internal stresses: The impact action of the shot flow on the metal surface helps to partially relieve residual technological stresses after welding or cutting, increasing the fatigue strength of the structure.
Service Delivery Format: Standalone or as Part of the Corrosion Protection Complex
Shot blasting cleaning can be performed as a separate service for third-party customers who need to thoroughly prepare metal before welding, mechanical processing, or their own painting.
However, the maximum economic and protective effect is achieved within the framework of a comprehensive anti-corrosion protection (ACP) service at our plant. The full cycle looks like this:
- High-precision metal processing (laser cutting).
- Shot blasting cleaning to Sa 2½ – Sa 3 degree.
- Technical control of roughness and surface purity (in accordance with ISO 8501 and ISO 8503).
- Prompt application of the primary primer layer (to avoid the appearance of initial film corrosion from the air).
- Final industrial anti-corrosion painting in our own paint booth (26 × 6 meters) with a service life of up to 25 years.
- Welding and assembly works to create finished structures.
FAQ:
- To what degree is the metal surface cleaned? — We provide the highest industrial cleaning degrees — from Sa 2½ to Sa 3 in accordance with the international standard ISO 8501.
- What are the guarantees regarding surface roughness? — The roughness parameter is Rz ≥ 40 µm in accordance with ISO 8503 requirements, which is an ideal indicator for applying long-term protective painting systems.
- What are the maximum dimensions and weight of structures that can be loaded into the shot blasting chamber? — The chamber is designed for processing large-sized products weighing up to 50 tons and measuring up to 24 × 3.6 × 3.6 meters.
- Can I order only shot blasting cleaning without subsequent painting? — Yes, you can order metal cleaning as a separate service before your subsequent work, or as a comprehensive turnkey anti-corrosion protection.
