Resistance to corrosion and chemicals
mateenbarTM is highly resistant to chemical attack and will not rust. This makes it ideal for marine applications such as coastal construction, chemical plants and other environments where steel is unsuitable. Design engineers working in such conditions select mateenbarTM to extend life-spans of concrete structures.
mateenbarTM is the ideal material for applications where minimal concrete coverage is required – since its corrosion resistance eliminates leaching and rust stains which would otherwise ruin the surface aesthetics.
Non-conductive and non-electro magnetic
mateenbarTM is non-conductive, therefore stray electrical currents cannot cause induction problems. It is ideal in high electrical fields where significant power is lost due to induction into the surrounding steel reinforcement. Additional savings can be realised as mateenbarTM reinforced structures can be located in the direct proximity of electrical fields. As a result, transformer buildings can be smaller and high current equipment may be installed directly on the reinforced slab.
Low thermal conductivity
The excellent insulation properties of mateenbarTM help ensure that concrete maintains a good thermal insulation value.
Easy to Cut
In tunnelling projects, mateenbarTM is specified for soft-eyes in the cages of piles and diaphragm walls. A Tunnel Boring Machine (TBM) can cut through the soft-eyes easily without risk of damage to expensive cutting equipment. Savings in down-time assist engineers keep projects running on schedule and within budget.
mateenbarTM can be cut quickly and easily with simple hand tools.
Close to magnetic apparatus – such as hospital MRI rooms, compass calibration areas and in high-current applications – steel reinforcement is unsuitable because the magnetic properties interfere with sensitive equipment.
These problems can be avoided by specifying mateenbarTM as the reinforcement for such applications.
Minimum moisture absorption
Moisture absorption must be minimised to ensure longevity of composites. mateenbarTM moisture absorption rates are extremely low, ensuring mechanical properties are maintained which extends the project life.
mateenbarTM offers the best price-performance in the industry
In applications where corrosion resistance is important, mild steel is unsuitable unless combined with an additional costly protection system such as:
• Bar coating – galvanized or epoxy coating
• Increased concrete cover
• Cathodic protection
• Special concrete admixtures
• Paint or membrane water-proofing and protection of the entire structure
Although these steel protection systems may delay the onset of corrosion, they increase costs and cannot prevent the inevitable. Steel protection systems must be executed on-site 100% accurately to avoid premature failure.
High-grade stainless steel is an option where on-site workmanship cannot be controlled. However, it is a very expensive material, and still suffers nodule corrosion.
Exotic alternatives such as epoxy steel and MMFX are also expensive materials, and although they may delay the inevitable, they do not actually solve the problem of reinforcement corrosion.
Steel based protection systems at best only delay the symptoms, whereas mateenbarTM solves the problems and guarantees a corrosion free solution at less than 40% of the cost of high-grade stainless steel without construction risks.
While the initial material cost of FRP rebar is higher than standard ‘black steel’ rebar (comparable to galvanised steel rebar), when evaluated on a lifecycle cost basis, FRP rebar delivers significant value in the form of cost savings associated with maintenance, repair, demolition and replacement cost savings.
Estimates indicate with a modest incremental 2-10% investment in the initial cost of the reinforced structure, the use of FRP rebar will result in a useful life in excess of 100 years (2-4x that of traditional materials) and expected lifecycle savings of 15-30% over other alternatives. mateenbarTM also offers reduced installation costs (via reduced on-site equipment, manpower used to move and position bars, etc.) and health & safety advantages (reduced lifting accident rates given lightweight material).
mateenbarTM is formulated from some of the most highly corrosion resistant materials available.
Precise process control ensures optimum performance is achieved from these materials for maximum durability. This is most critical in harsh environments where performance of other reinforcing materials may prove inadequate.
Manufacturing mateenbarTM consumes 25% less energy than that of steel production therefore it has a reduced carbon footprint.
Research and development
Our materials research scientists and R&D capabilities ensure that mateenbarTM utilizes the highest performing raw materials. mateenbarTM is manufactured from a proven epoxy backboned resin system to maximise corrosion resistance and increase inter-laminar shear strength. Carefully selected grades of glass fibre ensure immunity to alkaline attack and long life.
Glass content, fibre straightness, and the bond between fibres and the resin matrix are carefully controlled to achieve the high tensile strength of mateenbarTM.
Continuous quality control and a commitment to long term proven raw material suppliers ensure superior properties are maintained.
Modulus of elasticity
The modulus of mateenbarTM is optimised to ensure maximum benefit is achieved from the raw materials, offering designers a price/performance advantage.
The integral ribbed surface of mateenbarTM has improved durability as it does not rely on additional surface treatment or sand coatings to create the bond between rebar and concrete. The rib shape and pitch has been designed and tested to provide a superior bond strength compatible with commercial grades of concrete.
