What are the specifications of the heavy-duty shelves in general?
Generally below 200 kilograms, each weighing is light shelves (because light shelves are now low quality, serious, feel 100 kilograms are dangerous). Although the light shelf is the absolute main force on the market shelves, but we must pay attention to the quality, if there is quality and slightly heavier demand, or direct medium shelf. 200-500 kg each bearing is medium shelf, this specification is the most common storage shelves, all hanging shelves of the name, so it is also relatively reliable bearing, at least do the difference is one hundred kg, 200 kg of medium quality of every layer of the bearing can still, good quality standard the bearing is every 280 kilograms, actually to be higher.
Of course, shelf size classification, and I size classification, but this applies only to plywood shelves, other shelves are not classified by this. Heavy wood shelves size common with 200*60*200CM and 200*50*200CM, the more common dimensions are 150*60*50CM and 150*50*50CM, generally smaller size is not, the most common light shelf 120CM in heavy shelves are rare.
We are doing the shelves, Hercules brand shelves, shelves of our nominal is each bearing 280 kilograms, but with strict safety redundancy, redundancy value of not less than 1.6, less than 1.6 times the 280 kg is nominal can afford. 1.6 times, in fact, to 448 kilograms, nearly 500 kilograms of heavy shelves. We use the column (end bearing part of the shelf) is a U type column, the shape is generally heavy shelves only design, we used directly in the middle shelf, estimated that such usage in the market is also very little, after all, the usage of words, the shelf weight more than 1/3, of course, basically increase strength more than doubled. This column theory can bear the weight of 1000 kilograms, is more than a ton of the heavy layer (4 layer shaped body, which is the default) is to use higher weight, mainly for the above P beam and plate after each layer can bear the weight of 1 tons, of course, this is in fact will be the theory values. Leave the safety of 20%-30% value.
Generally speaking, according to the bearing weight heavy shelves every layer can load 500 kg from the shelves, the highest not side.
