We constantly work to improve our products and have done so over many years. This page briefly illustrates the products we use in your Texas steel carport or RV cover frame and some information on why we fabricate things the way we do.
Please take a moment to understand the unique characteristics of our metal carports and RV covers. Any explanations or pictures of similar products are furnished only for comparative evaluation.
You should know that Absolute Steel through its sister website Metal Roofing Source distributes metal roofing panels throughout North America and has done so for many years. We supply many companies and government agencies that have strict specifications with regards to the properties of the steel panels that are acceptable.
Don't let THIS happen to you!
To give you a real life example: if your painted exterior panels are going to be used in Cargill’s salt mines of Ohio with salty moisture dripping on them daily, which ours are, you’ve got to deliver the best and that’s exactly what we do:
- All steel panels have 80,000 ksi strength steel.
- Paint finish warranties of 25, 30 and 40 years against fading chalking or peeling.
- Underwriter’s Laboratory, the most trusted worldwide source for product safety certification rates the panels we use an industry leading: UL 2218 Class 4 hail impact rating and a UL 790 Class A fire resistance rating.
Now if the paint finish it guaranteed that long what do you suppose is happening to the steel underneath?
Nothing when you have an Absolute Steel Texas metal carport or RV cover!
Steel Frame System
There’s a lot we have to say about the US steel we use in our Texas steel carports and RV cover frames but for our purposes here, we need to discuss our fabrication process and why we make parts the way we do.
Base Rail System - A Superior Foundation
As the base rail system bears the maximum load of the structure itself, we do not use a swedged (mechanically reduced) piece of tube to fit up into the sidewall of your metal carport or RV cover. Instead we use single 14 gauge insert tube (insert tube is slightly smaller: 1 ¾” x 2 ¾”) for each vertical upright to slip onto. Why would we do this when we have the equipment to reduce/swedge the ends of 2x3 steel that we use throughout the frame and therefore could avoid this costly step?
The two reasons why are:
- At the bottom, where condensation can collect, you have uniform and tight connections where it is most critical to keep moisture out.
- 12" inserts give you plenty of adjustment capabilities in the event your site is irregular.

The BEST Connection
Side Walls - Easy to Assemble and Stronger
Common sense tells you that a sidewall that’s made up of more than one piece is not as strong as a single piece and yet that’s what the competition often does. The reason we use a single piece for the sidewall of your Texas steel carport or RV cover is pretty straightforward:
- Single piece connections that run from the base rail to the eave piece give you more strength on that wall.
- By not using multiple pieces for a sidewall, you have less assembly. That makes it easier on you or less money if you are paying an installer.
- Your steel carport or RV cover in Texas will have a wall that’s straight.
- You have parts that easily adjust without machining which adds up front costs.
Their Multi-Piece Sidewall
Only someone who wants to sell more
parts would use a multiple piece sidewall
- it’s not as strong and takes
more work to assemble.
Our Single Piece Sidewall
Because your sidewall is one piece
with our system, you’ll have
less parts to assemble
and a straighter wall.
Peak and Eave Bends - The Power Bend
Plain and simple, our Power Bend is the most superior technology in the tubular steel building business; its way out in front of the competition. That’s quite a statement but with the following information and a few pictures, you’ll know why we can make that claim.
First you need to understand that angles and curves—features you see on a car body are not just pretty, they’re necessary as they contribute to rigidity/strength of the steel. That’s why a piece of angle iron is stronger than a straight piece of steel strap.
There are several technologies used to make the bends at the peaks and eaves of a Texas steel carport or RV cover. Let’s take a look at some and compare:
Crush Bend: This bend puts a tremendous amount of stress on one isolated spot. It’s the cheapest, most structurally unsound way to accomplish a bend with steel tube. And to make a bad job worse, most of the Crush Bend structures we’ve seen are made with inferior quality 2.25” x 2.25” Mexican steel.
An uninformed person will buy this product which uses Mexican steel and Crush Bends for both the peaks and eaves. The price is attractive except when you consider you’ll be replacing it every year or two.
|Crush Bend Peak
Knowing the peak has been weakened by the Crush Bend, this company is using a 16 gauge U brace to give the weakened point more strength. (Doesn’t work but does show some diligence.)
|Crush Bend Eave
Notice the use of two crush bends, that’s because the Crush Bend is so radical it would tear the steel if one tried to make the necessary radius with one bend. As a side note, one panel screw used per side on a joint is simply inadequate and dangerous - and this is a sales model!
|Crush Bend Outcome
Apparently this carport is still for sale? Pay particular attention to where this structure gave in—right at the stress points; the crush bends despite any U channel bracing.
Mandrel Bend: This one claims to have "a stronger bend transition”. To debunk that statement one only has to look at the two pictures below. The lineal pattern on the inside and outside of the steel tube that underwent the "mandrel bend stretching process" is caused by stress lines in the steel. With a mandrel bend the steel is stretched and the stress marks are visible---and that’s what you can see.
This is not good.
The Mandrel Bend
The company that produces this makes the claim "smooth mandrel bend for a cleaner look and stronger bend transition”.
We beg to differ. You can’t stretch metal and make it stronger.
See the stress marks on the tube where its been stretched? Those are now severely weakened areas exactly where you don’t want them.
Power Bend: The Power Bend adds six more surfaces with condensed curves to strengthen peaks and eaves—remember the car body and why it has contours to its surfaces? The peaks and eaves need to be built that way because steel carports and RV covers are prone to stress at those points.
The Power Bend
The Power Bend is a result of rolling the excess steel
while the curvature is created. The rolled
edging now gives strength to the transition curve.
