How to fold steel?
I've always wondered how to fold steel to make it stronger
Basically, you get it really hot, rolled, folded in on itself and repeat. folding does two things. First, it helps to transform a raw piece of metal in a uniform bar (which is the important part). Secondly functions more carbon in the steel and realigns the crystals, and also gets rid of some of the impurities. http://www.youtube.com/watch?v=JfJn3r_-HuE&feature=related

The huge growth in demand for folding sliding doors in the last two or three years has led to a rapid increase in the choice of door systems available to the consumer. BI is also known as double doors every two folding doors, many times the doors and concertina doors that are better known as sliding doors folding due to the action of opening itself.

Although the original concept of a sliding folding door date more than 100 years, which is often used to close small storage areas, folding sliding doors today are designed to be energy efficient patio doors efficiently using the latest innovative insulation characteristics at the door and the glazing construction.
Folding sliding doors, not only allow for greater clear opening but the glass surface allows huge flows increased natural light to enter the house from the outside that during the colder months provide efficient use of solar gain to minimize heating costs. The doors are available in a variety of materials such as wood, aluminum and PVC-U, along with a selection of colors and finishes that will enhance any home.
WOOD
You can choose from a range of engineered wood folding sliding doors including softwood or hardwoods such as Meranti and European Oak. Wood is usually engineering or laminated to ensure it is structurally resistant to deformation or torsion and doors are normally available with either an application factory transparent stain or paint finish RAL color.
Since wood is a natural insulator wooden folding sliding doors offer the most efficient solution energy when combined with high performance double glazing offering U values as low as 1.4.
Wood folding doors often provide lines visibility thin door panels are normally individual hinged to each other without the use of additional amounts between each panel and thus maximize visible area glass.
Wood is a natural sustainable material that is very energy efficient, but require regular maintenance during the lifetime of the door to keep your stain or paint finish.
ALUMINUM
Aluminum folding sliding doors are usually made from durable, heat resistant broken aluminum profiles that are designed specifically for that purpose. These systems have been in use for several years in both domestic and commercial installations such as restaurants and hotels.

UPVC
Also referred to as plastic or PVC-U folding sliding doors of this type of door is relatively new on the market compared to aluminum or wood. Because of its low comparative cost of uPVC door manufacturers have quickly adapted their door profiles existing uPVC to create bi folding doors in response to an increasingly growing market that requires a more affordable system of folding doors. uPVC folding sliding the doors can be substantially cheaper than their aluminum or wood, but there is often a trade-off in design elements that can sometimes compromise the quality product.
Adaptation bulky steel reinforced uPVC range of profiles that were originally designed for traditional exterior door hinge meant glass sight lines were greatly reduced and the gates used ugly face and exposed hinges fixed gear also sometimes poses a safety hazard.
However, some manufacturers have begun introducing the new generation of folding doors uPVC profiles using thinner and hidden gears that compare favorably with wood and aluminum. Profile of heavy reinforcing steel is starting to be replaced by lighter materials but stronger compounds that are also recycled much more energy efficient.
