A typical rack in homes holds between 60 to 150kg worth of items on each level. If you have mainly loose items or crockery, it will be around 60-80kgs. If you love to keep magazines, a shelf full of them it will be between 80 and 150kg depending on the length of the rack.
I’m sure you have bought one of those racks from our favourite international DIY furniture shop. If it says max 100kg per level and you load it to 80kg, you are almost reaching the limit of the shelf. We bet that you’ll definitely see the shelf smiling curved at you.
Depending on the size of the rack, our capacity range from 200 to 400KG per level. The most common configuration for HDB storerooms has 350kg per level capacity.
Loading each level full of books and magazine to 150kg you’re only using about 40% of our shelf capacity!
If you have the excess strength capacity, you have safety guarantee. The last thing you want to see is a smiling rack spilling all your stuff on the floor after that.
