Expert practice in metal construction
In my work as Publicly appointed and sworn expert for the metalworking trade I regularly inspect damage, defects and execution errors in metal constructions.
The following case studies show typical damage patterns from practice - from Windows and facades about Stairs and railings up to Welded joints and corrosion problems in the industrial sector.
The aim of these examples is to identify the most common sources of errors in metal construction, whose Explain causes technically and Solution-oriented measures to be displayed.
Each case study is based on real expert opinions, is neutrally described and is intended to help building owners, planners and tradesmen, Detect and prevent damage at an early stage.
The cases presented illustrate this,
how important a Professional planning, execution and control in accordance with the applicable technical standards (e.g. DIN EN 1090, DIN EN 14351-1, DIN 18065, RAL installation guideline) is.
Whether Leaky windows, Contact corrosion, Insufficient weld seams or Errors in the coating - Every defect has its technical cause, which can be documented in a comprehensible manner by an expert inspection.
Overview of the case studies:
- Improper installation of windows - causes, consequences and expert assessment
- Corrosion on stainless steel railings - causes, assessment and renovation recommendations
- Inadequate welding - Weld seam defects in metal construction
- Flaking of the zinc coating - causes, assessment and remediation of coating defects
- Deflection of the staircase stringers - structural defects in metal construction
- Minimum distances between handrails - requirements in accordance with the Workplace Directive (ASR A1.8)
- Crack formation on weld seams - detection by dye penetrant testing (PT2)
- Pores and bonding defects on aluminum components - detecting and evaluating welding defects
- Zinc cracks after hot-dip galvanizing - causes, analysis and evaluation
- Glass roofing – Leaks and corrosion damage to brackets
- Incorrect design and installation of PVC windows - causes, consequences and assessment
