7 signs your steel structure factory needs inspection now!

      A steel structure factory must be regularly inspected and repaired to prevent deterioration that could pose risks to safety and disrupt production.

      1. Deflection or slight deformation of beams and columns

      Beams and steel columns for factories are the primary load-bearing components of a steel structure factory.              

      When there are signs of deflection, bending, or slight deformation. Even if the overall structure is not yet compromised, this is an early warning that the structure is beginning to degrade.

      Causes may include overloaded conditions, changes in functionality, or material aging. Early inspection and repair will help prevent severe deflection that could lead to collapse.

      2. Loose or rusted welds and bolts

      The welds and bolts in the steel structure factory are critical to maintaining its structural integrity. If welds show cracking, peeling, or if bolts are loose or rusted, these are clear signs of weakening.

      Minor issues can be fixed by reinforcing or replacing bolts. For more severe cases, comprehensive factory repair will be required to ensure safety.

      3. Appearance of small cracks on the structural surface

       Small cracks or micro-cracks on the surface of beams, steel columns for factory, or cladding sheets are also signs that the steel structure factory is experiencing excessive mechanical or thermal stress.

     Cracks can result from thermal expansion, dynamic loads, or construction errors. Routine inspections help detect and resolve these issues early.

      4. Strange noises when under load or in strong winds

      An often-overlooked but important sign is the presence of strange noises coming from the steel structure factory when subjected to strong winds or heavy loads.

      Sounds like "cracking" or "creaking" may indicate weakened joints, thermal expansion, or structural displacement. These signals require immediate investigation to prevent potential hazards.

      5. Unusual vibrations during operation

      If abnormal vibrations are felt in the steel structure factory during plant operations, this may indicate a reduction in overall stiffness and alignment.

     Such vibrations often result from foundation weakening, loose connections, or a compromised factory steel frame. Inspection, reinforcement, or replacement is necessary.

      6. Corrosion on steel surfaces due to chemicals or rain

     Steel structure factory buildings used in chemical industries, food processing, or exposed outdoor environments are particularly susceptible to corrosion.

      When steel surfaces show peeling protective coatings and rust patches, corrosion is already underway. Anti-corrosion treatment, repainting, or component replacement is required.

      7. Structural impact from forklifts or cargo

     Constant movement of forklifts, machinery, or collisions with pallets can also damage the steel structure factory.

      Minor impacts can cause deformations or dents in steel columns for factory or bracing members over time. Without prompt factory repair, these weak points may lead to major structural issues later.

      8. Why should you inspect the steel structure factory regularly?

    The steel structure factory is the core load-bearing system that enables long-term, stable operations. Without regular inspection and maintenance, hidden risks can result in:

• Increased risk of collapse.
• Production disruptions.
• Property and human losses.
• Higher factory repair costs later.

     Therefore, manufacturers should implement scheduled inspections and maintenance. Depending on production type and environment, inspection cycles should range from every 6 months to once a year.

      9. How to inspect and handle weak steel structure factory issues

     When any of the 7 signs appear, the first step is to conduct a full inspection of the steel structure factory by professional service providers.

     A reputable factory repair service will typically follow these steps:

• Detailed on-site survey.
• Assessment of structural damage.
• Proposal of appropriate factory repair solutions.
• Post-repair safety verification.

      If the issues are found in main load-bearing elements like steel column for factory or factory floor, priority handling is critical to ensure absolute safety.
