These scale kits allow you to build a livestock scale very inexpensively. We recommend a steel platform but you could use something like a wood platform if you're weighing lighter animals or objects. You don't want the platform flexing. However, for cattle, the platform would need to be more heavy duty steel or metal style frame underneath to bolt the load cells onto. Note: if you weld on the platform, make sure you do it before you have load cells installed.
