After 45 years of proudly serving our customers, dealers, and industry partners, Sun Welding has made the heartfelt decision to close our doors in October 2025. Since opening in 1980, our family-owned business has been built on craftsmanship, integrity, and relationships — and we are deeply grateful to everyone who has supported us along the way.
This was not an easy decision, but we are incredibly proud of what we’ve built together over four and a half decades. While we will no longer be accepting new orders or manufacturing products, we are not gone. We will continue to monitor email and can be reached at [email protected]for product-related questions.
From our family to yours — thank you for trusting us, supporting us, and being part of our story. It has truly been an honor.
With gratitude,
The Sun Welding Family
Sun Welding handcrafted Safes and Vault Doors from 1980-2025. View our impeccable quality in every one of our Custom Built Safe products. Sun Welding offered the only left-hand hinge safe standard and optional right-hand hinge safe. We provided personalized customer service with every build, from Vault Doors and Home Safes and more!
The fire rating on a Sun Welding safe is independently tested and rated. The problem with a safe fire rating is that none of the manufactures have tested the safes at the same facility, under the same specifications. There are many variations of fire testing and ratings for gun safes. Sun Welding would like to be UL Fire rated since they are the only honest testing facility, but they want too much money to test each safe. Sun Welding safes are proudly American Made Craftsmanship and Custom Built Safe, ensuring the highest quality and durability.
We offer many Custom Built Safe with different sizes and options that would need to be tested at very high prices for each. We have tested our safes in an oven that was 1200 degrees and at ‘x’ minutes (basic is 30 minutes up to 120 minutes) the internal temperature of the safe reached 350 degrees. Sun Welding also adds a fire proof safe gasket.
DESIGNED TO PREVENT SPREAD OF FIRE
The gasket is designed to prevent the spread of fire, smoke, and moisture by expanding seven times it’s size. The fire gasket fits against the door perfectly every time. Sun Welding uses a 5/8″ thick gypsum fire board to internally line the walls of the safes for fire rating, many competitors only use a 1/2″ thick piece of material.
