The L-type tension wound finning process involves wrapping aluminum or copper fin strips around the base tube under controlled tension. This creates optimal contact between fin and tube surfaces while protecting against atmospheric corrosion. All products receive zinc or aluminum electro-spray arc coating and include desiccants for transportation protection.
