Metal by nature does rust quickly when it encounters any moisture, so this is much more prevalent in the winter months. Lasered Components never stores any of our stock material outside and when it arrives on our premises, it is quickly stored appropriately in our dry and warm warehouse. Sometimes, customers will receive a part with surface marks on, which are hardly visible. This can look like rust, but sometimes it could be anti-spatter that’s used during the laser cutting process. This usually wipes off easily, and it isn’t rejectable.
