NEXCO specifications expansion device new product born! Obtaining NEXCO certification!
New product NEXCO certified | CF-20 | NCF type | 3LII-150 | 3LII-160 |
To adopt our products on the expressway (NEXCO), it is necessary to obtain certification in accordance with NEXCO's guidelines. Our lineup for NEXCO has traditionally included the CF type (expansion amounts of 30, 50, and 80mm) and the 3LII type (expansion amounts of 200, 250, 300, and 350mm). However, there was a gap between 80mm and 200mm, making it difficult to provide good proposals for projects requiring an expansion amount of 100mm. To address this demand, we developed the NCF-100 with an expansion amount of 100mm, and the 3LII-150 and 3LII-160 with expansion amounts of 150mm and 160mm, respectively. Additionally, we developed the CF-20 with a compact design and an expansion amount of 20mm, as well as the NCF type that can handle snow compaction. We are pleased to announce that these new products have received new certification from NEXCO. It is worth noting that the expansion amounts of 150mm and 160mm are close because the order documents may specify those exact expansion amounts. Please feel free to request materials or contact us at the timing of your product consideration before bidding or after winning the bid.

Company information
CRETEC, a company under Crittec Industries, was born from the combination of Create (creation) and Technology. As a comprehensive manufacturer of bridge expansion devices, we continue to develop expansion devices that contribute to the longevity of bridges and environmental protection. Moreover, we do not stop at product manufacturing; by consistently handling everything from research, design, manufacturing, sales, to construction in-house, we can manufacture and install expansion devices that meet the requests of our clients and general contractors, as well as the conditions and environments of the bridges and roads on-site. We also take into account the issues that arise during the installation of expansion devices and the damage conditions of existing devices that are removed, using this information to improve and develop our products. Please feel free to contact us for inquiries about bridge expansion devices, requests for materials, or estimates. ◆ What is a bridge expansion device? It is a component installed in the gap between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create a gap to prevent the bridge girders from colliding due to expansion and contraction caused by temperature changes. The bridge expansion device is required to cover this gap and ensure safe passage for vehicles and pedestrians.
