Due to prolonged and frequent use, metal frames in indoor children's play centers are highly prone to issues such as peeling paint, rust, and loose bolts. Unlike outdoor equipment, indoor facilities have humid air and frequent human activity. If minor rust and loosening are not addressed promptly, they will not only shorten the equipment's service life but may also lead to hidden hazards such as frame deformation, component detachment, and sharp burrs, directly threatening children's safety. Based on our equipment maintenance experience, Playpedia Amusement has compiled standardized procedures and preventive measures tailored to the maintenance needs of various types of indoor non-powered play equipment.
I. Explanation of Equipment Hazards
Rust on metal frames gradually corrodes the steel substrate, reducing the equipment's load-bearing and impact-resistance capabilities. Rust-induced burrs can also scratch children's skin. Loose bolts and weld points cause abnormal noises and shaking during operation; over time, this leads to structural misalignment and component detachment. These are the most commonly overlooked causes of safety incidents in indoor playgrounds and are key inspection items during annual equipment inspections.
II. Standard Rust Treatment Procedures
We adopt graded treatment methods for slight, moderate and severe rust on indoor adventure park equipment. Painting over rust directly for a quick fix is strictly forbidden.
1. Slight surface rust and paint peeling
First, wipe off dust and stains on the kids indoor playground equipment frame with a dry cloth. Use fine sandpaper to sand the rusted areas evenly. Remove all surface rust and leftover paint completely until the metal base is smooth and exposed. Wipe off all dust after sanding, then spray a uniform layer of professional anti-rust primer. Once the primer dries, apply matching topcoat to restore the equipment's protective layer.
2. Local rust spots and small-area corrosion
Apply rust remover to corroded areas and soak the spots to soften hard rust, then clean the areas thoroughly. Pay close attention to damp and hard-to-clean parts, including slide joints, climbing frame connections and the bottom of equipment frames. After cleaning, apply two layers of anti-corrosion coating to stop rust from coming back.
3. Severe rust and metal thinning
Do not repair equipment with perforations, large-area corrosion or rust-caused deformation on load-bearing parts. Stop using the indoor soft playground equipment immediately. Replace it with original parts of the same standard to avoid safety accidents.
III. Standard Procedures for Loose Frame Parts
Indoor play equipment endures constant vibration from children running and climbing. This easily loosens bolts, welding joints and fasteners. All loose parts must be tightened and reinforced in standard ways. Do not use brute force during operation.
1. Common loose bolts
Check all connecting bolts, nuts and spring washers on the equipment thoroughly. Tighten them properly with standard wrenches. Control tightening force well to avoid thread slipping or frame deformation. For parts under frequent stress, fit anti-loosening washers or apply thread-locking glue to improve stability. Mark a straight alignment line after tightening. This helps staff spot loose parts quickly in daily checks.
2. Stuck or rusted connectors
Never force rusted or stuck bolts loose. Apply professional lubricant first and let it soak for 5 to 10 minutes to soften the rust, then turn the bolt slowly. Replace heavily corroded or worn parts directly with stainless steel accessories. These parts work better against rust and loosening.
3. Loose welding and frame joints
If you find welding cracks or loose frame connections, block off the equipment at once. Arrange professional technicians to re-weld and polish the surface smoothly. Apply anti-corrosion coating afterwards. The commercial indoor playground equipment can only be reused after passing safety inspection.
IV. Daily Preventive Maintenance Guidelines
The core rule of indoor soft play equipment maintenance is prevention first, remedy second. Proper daily maintenance can greatly reduce rust and loosening problems.
Check frame connections and rust conditions before and after daily use. Wipe off moisture and stains from equipment surfaces every week.Conduct full bolt tightening and structural inspection every month. Keep the indoor venue well ventilated and dry to prevent rust caused by long-term dampness. Touch up chipped paint regularly to eliminate hidden dangers in advance.
Standard maintenance work protects children's safety effectively. It also extends the service life of indoor playground equipment and cuts facility repair and replacement costs. This is the key to stable and long-term operation of indoor play centers.
