Metal brackets are widely used in many industries such as construction, elevators, bridges, mechanical equipment, automobiles, new energy, etc. In order to ensure their long-term stable use, regular maintenance and correct maintenance are essential. This guide will help you improve the service life of the bracket and reduce maintenance costs from the aspects of daily inspection, cleaning and protection, load management, regular maintenance, etc.
1. Daily inspection: the first step to prevent problems
Regularly check the structure and connection parts of the bracket to detect potential problems in time. It is recommended to conduct a comprehensive inspection at least every 3-6 months.
● Check the surface condition of the bracket
Observe whether there is rust, corrosion, peeling, cracks or deformation.
If the paint on the surface of the bracket is peeling or the protective layer is damaged, it should be repaired as soon as possible to avoid further corrosion.
● Check the connection parts
Check whether the bolts, welding points, rivets, etc. are loose, damaged or rusted.
Make sure all fasteners are stable. If they are loose, they should be tightened or replaced.
● Check the load condition
Make sure the bracket is not overloaded, otherwise long-term high load will cause structural deformation or fracture.
Re-evaluate the load-bearing capacity of the bracket and adjust or replace the reinforced bracket if necessary.
2. Cleaning and protection: avoid corrosion and pollution
Stands of different materials require different cleaning and protection measures to extend their service life.
Carbon steel/galvanized steel brackets (commonly used in construction, elevators, mechanical equipment)
Main risks: Easy to rust after being damp, and damage to the surface coating will accelerate corrosion.
● Maintenance method:
Wipe with a dry cloth regularly to remove surface dust and water accumulation to prevent rust.
In case of oil or industrial dust, wipe with a neutral detergent and avoid using strong acid or strong alkaline solvents.
If there is slight rust, lightly polish with fine sandpaper and apply anti-rust paint or anti-corrosion coating.
Stainless steel brackets (commonly used in humid environments, food processing, medical equipment, etc.)
Main risks: Long-term contact with acid and alkali substances may cause surface oxidation spots.
● Maintenance method:
Wipe with a neutral detergent and soft cloth to avoid leaving stains and fingerprints.
For stubborn stains, use a stainless steel special cleaner or alcohol to wipe.
Avoid contact with high concentration of acid and alkali chemicals. If necessary, rinse with clean water as soon as possible.
3. Load management: ensure structural safety and stability
Brackets that carry more than the designed load for a long time are prone to deformation, cracking, or even breaking.
● Reasonable load control
Use strictly according to the rated load-bearing range of the bracket to avoid overloading.
If the load increases, replace the bracket with a higher strength bracket, such as thickened galvanized steel or high-strength alloy steel bracket.
● Regularly measure deformation
Use a ruler or laser level to check whether the bracket has deformation such as sinking or tilting.
If structural deformation is found, it should be adjusted or replaced as soon as possible to avoid affecting the overall stability.
● Adjust support points
For brackets that need to bear large loads, the stability can be improved by adding fixing points, replacing high-strength bolts, etc.
4. Regular maintenance and replacement: Reduce long-term maintenance costs
Develop a maintenance cycle and arrange regular maintenance according to the use environment and frequency of the bracket to avoid shutdowns or safety accidents due to failures.
● Recommended maintenance cycle for brackets
Usage environment Maintenance frequency Main inspection contents
Indoor dry environment Every 6-12 months Surface cleaning, bolt tightening
Outdoor environment (wind and sun) Every 3-6 months Anti-rust inspection, protective coating repair
High humidity or corrosive environment Every 1-3 months Corrosion detection, protective treatment
● Timely replacement of aging brackets
When serious rust, deformation, load-bearing reduction and other problems are found, new brackets should be replaced immediately.
For brackets used for a long time, consider replacing them with stainless steel or hot-dip galvanized brackets with stronger corrosion resistance to reduce maintenance costs.
Whether it is industrial application or building installation, correct bracket maintenance can not only improve safety, but also save long-term costs and provide enterprises with more efficient operation guarantees.
