Sun Welding’s H48 Heirloom Series Fireproof Home/Office Fire & Burglary Safe is an American Made safe and is one of the highest quality & most beautifully finished home security safe you can find with the most affordable prices.


High-Security Features

The H48 Heirloom Series High-Security Fire & Burglary Safe features 3/16-Inch thick solid steel plate doors and solid 7/64-inch (12-Gauge) frames.

It also features an EMP-resistant, Group 2 combination lock or electronic lock, which is protected by a ¼-inch drill-resistant hard plate, and an additional ½-inch absorption plate to resist impact or punch attacks.

And unlike many other safes in the industry, which features only one re-locker, the Heirloom Fire & Burglary safe features two (2) spring-loaded relockers to protect the lock and secures the safe even if the lock is completely destroyed.

The Heirloom Series Fire & Burglary Safe exceeds UL RSC and DOJ Requirements. It is American Made with the highest quality materials and backed by a lifetime warranty!


 SunWelding Heirloom Product Description Creative - Security Features Overview


  • Maximum Protection from Pry-bar and Crowbar Attacks with 3/16-Inch Thick Solid Steel Plate Doors: The doors on the Heirloom series safe is reinforced by a 3/16-inch thick solid steel plate, which is stronger steel than what other leading competitors are offering. This means that it will be almost impossible for a burglar to ever use a pry-bar or crowbar to break into this safe. 
  • Sturdy, Durable and Drill-Resistant 7/64-inch (12-Gauge) Solid Steel Body/Frames: In addition to the sturdy doors, the body of the Heirloom series is built with thick 12-gauge steel. This is stronger than other common fire & burglary safes and protects your safe against drill & power-tool attacks.
  • More Protection Against Pry-Bar and Crowbar Attacks with Recessed Doors: The recessed doors means that it is very difficult for thieves to jam their pry-bar or crowbar between the gaps in the door and break into this safe.

Sun Welding constructs the doors and body with only SOLID steel to ensure maximum strength and security of your safe. Most other manufacturers make safes with doors and bodies that may look thick, but they are actually filled with composite drywall (with very thin slabs of steel). They may look strong, but they’re actually quite weak!


  • No Weak/Vulnerable Attack Points with Continuously Welded Steel: The attention to detail and meticulous welding of this safe means that there are absolutely no weak spots on all sides of this safe, making it very difficult for burglars to break into the Heirloom series safe!


This is unlike what most manufacturers do, which renders their safe susceptible to “skip-welding”. Skip-welded safes mean that some areas may not be welded as well as others, creating weak spots for burglars to take advantage of.


 SunWelding Heirloom Product Description Creative - Security Features Overview


  • Drill & Punch Resistant Boltworks: The door bolts of this safe has been reinforced and protected to make it one of the most secure door bolts on the market that is resistant to extreme drill or punch attacks. In total, there are (15) 1-inch diameter doors bolts that protect all sides of the doors. 
  • (2) Re-Lockers to Protect Door Bolts & Lock and Secures Safe Even if Locks Are Completely Destroyed: Unlike most safes, which only has one relocker to protect the lock, Sun Welding’s safes have two to secure your safe from being breached even if the locks are destroyed. 
  • (2) Drill-Resistant & Anti-Punch Hard Plates to Protect Door Bolts and the Lock: In addition to the (2) relockers, the bolts and locks are also protected by (2) hard plates. One ¼-inch drill-resistant hard plate protects the lock from drill attacks, while the other ½-inch punch-resistant hard plate protects the door bolts from punch attacks.

When it comes to door bolts, the thickness is not everything! What matters more is how the doors bolts are protected and designed. Sun Welding’s bolts are protected by drill-resistant hard plates and are long enough to extend behind the frames for additional protection. Most safe manufacturers may create bolts that appear thick, but are largely unprotected and short, making it very susceptible to drill or punch attacks. 



Fire Protection Features

All of Sun Welding’s Heirloom Series Safes undergoes stringent fire-testing procedures and has been shown to protect your valuables against extreme heat & smoke. Not only that, but Sun Welding also offers you 4 different levels of fire protection to match your needs exactly!

SunWelding Heirloom Product Description Creative - Fireproof Features Overview


  • Up to 90 Minutes @ 1,200F Fire Protection: Depending on which upgrade you select, your safe can have up to 1.5-Hour of fire protection at 1,200F. This means that your safe’s internal temperature will not exceed 350F in the allotted time.
  • Protection Against Heat & Smoke with an Expanding Fire Seal: When exposed to heat, the seals on the doors will expand up to 8x its own size, thereby creating an extremely tight seal around the doors to keep away heat and smoke!


The External Hinge Advantage Sun Welding Safes are built with external hinges. Not only are external hinges just as secure as internal hinges, but external hinges also allow for a tighter seal around the doors to protect against heat and smoke. Why? Because there is no need to create gaps in the seal to make room for these internal hinges!


  • No Hot Spots with Continuously Welded Steel: When it comes to extreme heat, the first vulnerable spot for your safe is anywhere the safe was not properly welded (or skip-welded), which happens a lot in other big-box safes. Sun Welding’s safes have been meticulously welded to avoid skip-welding, protecting your safe’s interior from extreme heat!
  • Maximum Fire & Heat Protection with ⅝-Inch Fireboards: The fireboards used in this safe is 25% thicker than the ½-inch fireboards used by most safe manufacturers.


Other Exterior/Interior Features

The Heirloom Fire & Burglary Safes are not only made for security and fire-resistance, but they are also made to be beautiful both inside and out. Not only do you have the option of having multiple finishes and interior fabrics, but each safe is hand-crafted to give you the most beautiful and luxurious experience (without paying the big bucks!)


SunWelding Heirloom Product Description Creative - Exterior and Interior Features Overview


  • Beautiful Hand-Crafted Exterior Finish: Choose from either a matte gray finish or from a variety of gloss paint finishes. And whatever you choose, all of Sun Welding’s safes are hand-painted and finished with hand-applied logos. The Heirloom series safe also comes with a 5-spoke handle for a beautiful finishing touch!
  • Tailor Your Storage Needs With Customizable Interiors: Sum Welding offers 3 different rifle configurations or a solid collected shelf interior to match your unique storage needs exactly.
  • Store As Much As You Want with High Capacity ¾-Inch Particle Board: Sun Welding has hand-built interiors made from solid ¾-inch particle boards for high load capacity to ensure durability and strength to store whatever you need to store! 
  • Protect Your Valuables and Experience Luxury with Velour Fabric: Choose from a variety of luxurious velour fabric to protect your guns & other valuables from scratches.

Proud to buy a sun welding safe since they are american made.

Still going strong!

Purchased my sun welding heirloom h48 safe a couple years back. I moved around abit throughout the years and it still performs great. If I ever were to consider expanding my gun safe collection I would not hesitate to buy a Sun welding safe through these guys. Consider it folks.

Harold T.

I definitely do my research before buying my stuff because I care about quality. I spent months researching all the different safes and finally decided to go with a Sun Welding Heirloom Series Safe. At first I was looking into a TL15 or TL30 safe but I felt skeptical about them. I just don't believe any certified testing can really justify that price. Plus I highly doubt that my Sun Welding safe would fail their tests. I did take a look into Amsec, Brown and Graffunder safes but the rest were either too expensive or did not meet my size requirements. This safe is really the best bang for your buck, quality craftmanship, and I would think, would rival a TL15 or TL30 without the cost.

Ruben S.

Did my homework and couldn't find a better safe than this sun welding one right here. Glad that it's USA made.

Kenny D.

The customer service throughout my experience was top notch. They always got back to me on my inquiries.
