How to properly protect the walls? Are there any overall solutions for wall protection? 

Wall Protection Comprehensive Guide: One-stop Solution for Wall Protection with Anti-Collision Handrails and Wall Guards 

Wall protection mainly includes measures such as anti-collision, moisture-proofing, anti-staining and structural reinforcement, including handrails. Anti-collision handrails are an important part of the wall protection system, serving both the functions of assisting walking and protecting the wall. 

Core protective measures:

‌Install anti-collision handrails‌: Composed of PVC/ABS panels and aluminum alloy cores, they absorb impact forces through elasticity to prevent hard objects from directly damaging the walls. They are commonly used in hospitals, nursing homes, and corridors.

‌Lay wall protection panels‌: Install strip-shaped or entire panels (such as solid wood composite or plastic sealed packaging materials) at the lower part of the walls. They are shock-resistant and easy to clean, effectively resisting daily bumps.

‌Use anti-collision corner/strip guards‌: Install dedicated guards for vulnerable areas such as corners and door edges to avoid wall peeling caused by sharp collisions. 

Description of the armrests

‌It is a safety measure‌: The anti-collision armrest is not only an accessibility facility, but its "protective wall" feature clearly places it within the category of wall protection. It can reduce the direct impact of trolleys, wheelchairs or human bodies on the wall.

‌Key parameters‌: The installation height is usually 850mm-900mm (for double layers, it can be set at 650mm-700mm), the spacing of the support frame is 800mm-1000mm, and it is necessary to ensure that the load exceeds 100kg and maintain a gap of more than 40mm with the wall to prevent the back of the hand from rubbing against the wall.

‌Applicable scenarios‌: Widely used in corridors, stairs, bathrooms and wards. It needs to be fixed with expansion bolts or through-wall bolts according to the wall material (concrete, hollow bricks, etc.). 

It is recommended to combine the above measures according to the usage scenario (such as public institutions focusing on anti-collision and antibacterial, and families focusing on moisture-proof and wear-resistant). To achieve the best protective effect.
