FAQ’s
WHAT IS EXTEND SYSTEM?
It is a system specially designed to reinforce roofs and beams in poor condition. It is used to both replace and to reinforce existing beams
WHAT PROBLEMS DOES IT SOLVE?
EXTEND SYSTEM beams are used to replace or reinforce beams with:
- Carbonation
- Aluminosis
- Woodworms, parasites and termites
- Oxidation of iron beams
- Reinforcement of loads due to change of use
WHEN IS IT NEEDED?
A competent technician must analyze the roofs in question to diagnose the need for repair or reinforcement.
WHY ARE EXTEND SYSTEM BEAMS MADE OF ALUMINUM?
Rehabilitation works and beam reinforcements are often carried out in inhabited houses and in places that are difficult to access with iron, concrete or wooden beams.
The advantages of aluminum are:
- Adds little weight to the structure
- Strong material, high strength alloy
- Easy to maneuver
Concrete and steel beams are very expensive to install. EXTEND SYSTEM beams are made of an aluminum alloy so they weigh very little, approximately a third of what an iron of similar resistance weighs. In addition, being telescopic, they are transported disassembled to the place of their placement.
WHAT CERTIFICATION DO EXTEND SYSTEM BEAMS HAVE?
Technical Suitability Document – DIT (270R / 09)
CE mark
HOW ARE EXTEND BEAMS MOUNTED?
The assembly is very simple:
- Chipping of the damaged beam base
- Placement of supports
- The profiles are assembled telescopically by inserting one piece inside the other and they rest on the supports
- Retouched with mortar without shrinkage
HOW MUCH HEIGHT DO WE LOSE WITH THE STRUCTURAL REINFORCEMENT?
It depends on the profile that we must place and on the following factors:
- Loading
- Length
- Inter-axis
And it also depends on the mounting system
- Beam under beam
- Beam between beam
Do not hesitate to contact us and we will study your case!
DO EXTEND PROFILES HAVE TO BE WELDED?
EXTEND SYSTEM is the only system that does not require welding or screws. The profiles are assembled one inside the other in a telescopic way so that they work as a continuous beam. Welds are dangerous and toxic, especially if applied in inhabited buildings.
HAVE THERE BEEN TRIALS TO GUARANTEE THE SYSTEM?
Yes. Multiple and satisfactory tests have been carried out in the following laboratories:
- Polytechnic University of Catalonia
- Construction Laboratory of the Generalitat de Catalunya
- Laboratory of the Eduardo Torroja Institute of Madrid of the CSIC (DIT)
DO EXTEND BEAMS REQUIRE MAINTENANCE?
No. Because they are made of aluminum, The EXTEND SYSTEM beams require no painting or maintenance. We use 6063 aluminum alloy; whose properties are lightness and resistance to corrosion and the passage of time.
HOW MANY PIECES IS THE BEAM MADE OF?
EXTEND SYSTEM beams are made up of two or three sections depending on the total length of the beam to be reinforced and the difficulty of access to the location of its placement. Our technicians will advise you on the best solution in each case. You can consult us without commitment.
SAFETY IN CASE OF FIRE, WHAT IS THE BEHAVIOR OF THE EXTEND BEAM?
EXTEND SYSTEM beams must be protected against fire damage in order to comply with the regulations contained in the CTE-DB-SI, in the same way that steel beams must be protected with fire-retardant material.
WHY ARE BEAMS TELESCOPIC?
EXTEND SYSTEM beams consist of two or three pieces.
Using a telescopic system allows for the exact adjustment on site to the desired length.
HOW TO CALCULATE WHAT BEAM I NEED?
With the calculation abacus
- Enter the inter-axis column
- Select the total load to be considered
- In the beam length row, determine the length to reinforce
- The intersection determines the necessary beam
