When you purchase a steel door from Schweiss that's what you get!
All-steel doors are :
Using wood in place of steel members...
Stacking wood on steel members...
An all-steel welded frame gives you a stronger door!
Doors flex while moving up and down. . .
a welded connection is far better than screws
A 10-foot-long utility grade 2x4 is only capable of resisting a 23 mph wind. A 10-foot-long 2x3-14 gauge steel member is capable of resisting a 120 mph wind! What do you think that would do to your utility grade 2x4?
Two tec screws in the end of a 2x4 are good for about 40 PSF of wind if the screws don't split the wood. If the wood splits, the screw is good for nothing. Installation of the screws is critical and is all up to the erector. A 2x3-14 gauge steel member welded all around is good for about 120 PSF of wind. The steel is shop-welded, meaning no field labor is required. There are no tedious screws to install. Every member of an all-steel door is positively welded in place.
All wood is not created equal. Quality wood is clearly identified. It is grade stamped "SELECT". It doesn't have large knots and splits. Even if the wood was "SELECT", it would only resist a wind of 12.3 PSF. Does this seem strong enough for your door? Steel is a uniform material. Steel is a consistent grade and strength. When you get an all-steel door you know that the material quality is consistent.
Doors are flexible. The door will flex when wind blows on it and when it opens, the wind blows every day! Sometimes the wind is strong, other times there is almost no wind. You purchased a door so that you could open it. As the door flexes due to the variable wind load and its own weight, when you open it the screws stretch in the wood, eventually working their way loose, or worse, tearing out of the end of the 2x4. Welds never work loose. Welds are strong and permanent. They never need to be reinstalled or tightened.
Schweiss Uses All-Steel Members
Strong Welded Connections...
Internal Truss on this door
External Truss available
Small Tech Screws used to hold the wood on.
Using metal and an all-welded metal frame the connection is stronger than a screw connection
Less structural strength to the door when using wood over steel. Welded connections are stronger!
Stacking Wood on top of each other adds unnecessary weight to the door.
All-Steel is better, stronger, and has a neater appearance!
