Surface Preparation & Painting

The service life of fabricated equipment depends on its coating as much as on its steel. Simgetek carries out surface preparation and painting in its own facilities, in a dedicated area of 1,000 m².

 

Blasting, coating and curing are therefore planned as part of the production sequence, not as a step handed over to an outside applicator at the end of the job.

Surface Preparation

  • Automatic blasting lines — conveyor-fed vertical and horizontal machines with abrasive recovery, used for the continuous preparation of plate and section material
  • Manual blast booth — an insulated, enclosed booth of approx. 438 m³, allowing completed equipment and large assemblies to be prepared in one piece
  • Portable wet abrasive blasting — for site work and for parts that cannot be taken into the booth
  • High-pressure hot and cold water cleaning — to remove contamination before coating

Paint and Coating Application

  • Airless spray application with pneumatic and electric high-pressure units
  • Mechanical paint mixing to achieve the right homogeneity before application
  • Application of multi-coat systems in line with the project coating specification
  • Application planned with regard to ambient temperature, humidity and dew point conditions

Surface Treatment of Stainless Steel

  • Stainless steel parts are processed separately from carbon steel work, which protects the passive surface layer and prevents cross-contamination.
  • Cleaning and passivation of stainless steel surfaces
  • Segregation of stainless steel and carbon steel work areas and hand tools

Coating Quality Control

Coating work is verified at every stage, not only on completion:

  • Surface roughness measurement after blasting
  • Soluble salt testing of the prepared surface
  • Digital dry film thickness measurement
  • Holiday (porosity) testing of the applied coating
  • Monitoring of ambient conditions during application

Measurement results are recorded and provided as part of the project quality dossier.

Why It Is Done In-House

  • Fabrication and coating are scheduled together; delays caused by outside applicators are eliminated
  • Surface defects are found and corrected while the equipment is still in the workshop
  • The risk of damage during transport to and from an outside coating facility is eliminated
  • Coating records become part of the same quality documentation as the fabrication
