For more than five years and across 100,000 km of aluminum profiles, One Stack has been a manufacturing partner to Sika, one of the leading names in specialized construction and infrastructure solutions, supplying aluminum extrusion profiles for expansion-joint systems as well as for bonding, sealing and wrapping applications. Each application brings its own requirements: expansion-joint profiles must account for joint width and movement, substrate conditions, exposure to water or chemicals, traffic loads, fire requirements and installation orientation, and each of these shapes the specification, material and manufacturing approach. Alongside complementary PVC extrusion, One Stack provides the manufacturing flexibility to meet these varied specifications and the production consistency to deliver them to standard on every batch.
