Founded in 1995, Onward Chemicals is a fairly young company with a strong presence in the Indian Road and Infrastructure industry. Over the past 16 years, Onward has built this high dependability in its operations and has consistently maintained business relationships that you can count on.
We began operations as a distributor of Specialty Raw materials for the surface coating industry serving customers across India. We diversified from serving the conventional paints industry and the coatings segment and realigned our business to emerge as the preferred suppliers of high quality products for the road and infrastructure sector.
Onward has now taken yet another significant step in leveraging our experience and expertise by introducing an innovative product for the construction sector - Fibrex™ brand of Glued steel fibers in India. Glued steel fiber is known the world over for its versatility in application, ease of construction and cost savings.
Onward is continuing its efforts in creating awareness of the product, by reaching out to consultants, design engineers, construction companies and government organizations. We aim to popularize the product, make it available in every part of the country and bring the consumption levels on par with Europe, USA & Japan. The product applications of Glued Steel Fibers are wide and varied, significant among them being slabs & flooring, shotcrete, precast and structurals.
At Onward, we follow a simple Philosophy...
When we conduct our business with low tolerance to defects, quality issues and services mishaps, what you get is high dependability in our business relationships. The exact quality with the compliances you require, supply at the right time with planned logistics, and prices that are attractive when compared to the competition.
Glued Steel Fibers are cold drawn steel fibers, glued together to form bundles and deformed to have hooked ends. They are manufactured by repeated mechanical drawing of low carbon steel wire rods, until the specified thickness is attained. The individual fibers are glued together by means of water soluble glue, to eliminate formation of fiber balls (bunching of fibers) during concrete mixing process.
Fibrex™Glued steel Fibers conform to ASTM A 820 & EN 14889-1: 2006 standards.
Fibrex™has high tensile strength, hence the capacity to bear high load and absorb deformation. The hooked ends anchor in to the concrete, enabling the transfer and distribution of stress effectively. Due to its small volume, the steel fibers are fully enveloped by alkaline concrete matrix, rendering it corrosion resistant. Hence corrosion resistance of Glued Steel Fiber is considerably higher than other reinforcing steel.
Fibrex™Glued steel Fibres concrete absorb and dissipate energy more efficiently than normal concrete without fibers. Hence normal concrete is brittle while concrete with Fibrex ™ is ductile.
High energy is required to pull out Fibrex ™ fibers from the concrete matrix, hence the flexural strength is high. The fibers offers post crack ductility- i.e Normal concrete would completely collapse on cracking (Brittle behavior) , while concrete reinforced with Fibrex ™ would continue to bear load even after cracking (Ductile behavior).
Glued Steel fiber concrete offers high impact resistance & performance under dynamic loading. The improvement is due to reduction in stress concentration and better anchoring of fibers to aggregates in the matrix. Improvement in wear ability by 50% & fatigue resistance by 100% (Typical values) are observed in comparison to normal concrete without steel fibers.
Glued Steel Fibers can partly or wholly replace re-bar & mesh in applications, offering cost savings & convenience in construction. Steel fibers can be added in concrete mixer along with other materials during mixing. Hence, these are easy to incorporate unlike mesh and re-bars, which are cumbersome and take time to fix and align. Due to its high reinforcement capacity, reduction in slab thickness to the extent of 20% is possible. This effect in considerable savings on material and time.
The fibers impede crack formation and development of hairline cracks in to major cracks by acting as tiny bridges. This not only provides better cosmetic looks but also makes the concrete impervious to water (leaks).
Flexural toughness improves on addition of Fibrex ™. Concrete with Glued Steel Fibers offer improved abrasion resistance, cavitation resistance and erosion resistance, which makes them an ideal choice for dams, canals, ports & bridge decks.
Glued Steel Fibers perform better than locally made loose fibers. These mix well with concrete unlike locally made loose fibers which tend to form fiber balls. Fibrex ™, due to high aspect ratio has better reinforcing capacity than loose fibers, hence lesser quantity is needed in comparison.
