Crews battled a fire on Aero Park Court in Traverse City Monday morning.
The fire was at the Century Sun metal treating plant in Traverse City.
Fire crews responded to the call shortly after 11 a.m.
Seven employees were working in the building. All of them were evacuated. No one was injured.
"Century employees will muster together and we will rebuild this and be back in operation relatively soon, it'll be their finest hour," said Bill Janis the owner of Century Sun.
Fire crews say a tempering oven caught on fire but they are still investigating the reason for it catching on fire.
Tempering ovens are used in the metal treatment process.
"Most of the damage was segregated into one part of the building where the tempering ovens are, the rest of the building probably sustained a little bit of smoke damage," said Traverse City Fire Chief James Tuller.
Tuller said most of the fire was caused by burning wood pallets and materials.
The chemicals they were dealing with on site were "non-hazardous materials", but Tuller said Hazmat crews were there as a precaution.
The responding fire departments were Traverse City Fire Dept., Grand Traverse Metro Fire Dept., and Peninsula Township Fire Dept.
Tuller said the Century Sun employees who were working Monday were a huge help in fighting the fire.
"They're invaluable in helping us fight the fire, they know this plant like the back of their hand, when we had to make decisions regarding fighting the fire they were right there next to us," said Tuller.
Crews said there was significant damage to the area with the tempering oven, but the rest of the building may be ready to be re-opened as early as Tuesday.
