Designing:
Annual maintenance method of steel structure plant:
1. After the installation of our steel structure workshop, the
owner is not allowed to privately change its structure, remove the
bolts and other parts of _, or increase or reduce the partition
wall. If any parts need to be changed, the owner can consult with
the manufacturer and decide whether the change can be made.The
steel structure should be maintained with paint after about 3 years
of use, so as to give the building with beauty and safety.
2. Steel structure workshop should be cleaned and maintained
regularly. Under normal circumstances, inspection and maintenance
should be carried out once a year.When cleaning the outer wall of
the steel structure workshop, we should pay attention not to mess.
We should not use the steel wire ball, brush and other abrasive
cleaning products. When using clean water, we should wash from top
to bottom.Steel structure plant branches, leaves and other similar
objects should be cleaned up in time, so as not to backlog caused
unnecessary trouble.If there is any damage to the surface of the
metal plate in the steel structure workshop, it should be repaired
in time to avoid the corrosion of the metal plate by sun and
rain.If necessary, all the high elastic nano materials are applied
to protect the metal roofing panels, and play an effective role in
heat insulation and waterproof, saving indoor air conditioning
energy.
