The durability of bridges
Bridge structures of any size — regardless of material and purpose — are always extremely complex engineering objects that require maximum attention to every detail. During the construction of a bridge, no element can be neglected, because even a small mistake can affect the integrity of the entire structure.
Of particular importance is the protection of structural, reinforcing, or special steel elements that perform a supporting and fixing function in the bridge body.
Since most bridges are located near water bodies, their steel components are constantly exposed to high humidity. Therefore, anti-corrosion protection and preservation of metal strength are key conditions for the durability of the structure.
Taking these factors into account, TM "Arfen" has developed an optimal system of expansion joints for roads and bridge crossings . They consist of solid steel parts and an elastic rubber gasket that absorbs and evenly distributes the load.
Such seams compensate for deformations and shrinkage of the structure during operation, maintaining its stability.
The rubber component not only protects the concrete base from crushing and destruction, but also ensures complete tightness at the points of contact with the concrete and from the outside. This reliably isolates the steel elements from constant moisture, preventing corrosion and increasing the service life of the entire bridge crossing.
Arfen TM expansion joints are a reliable solution for bridges and roads designed for high and regular loads. The use of this technology ensures the strength, safety and durability of transport infrastructure.
