Tertu Crossings Douglas fir: the specie with a big heart Expertise Tertu s international development has enabled us to acquire expertise in deployment in wide-ranging geographical environments. 100 % service: the coordination Pre-sales, we select the most appropriate wood or wood & steel solution for you from a complete, homogeneous range. After sales, we shall be at your side during and after installation. If necessary, the design of the system facilitates repairs, which are carried out quickly in a spirit of partnership. On account of its structure, the Douglas fir is a natural choice as it is an exceptional material in terms of quality and natural durability. Its heart is deemed to be rot-proof. By 2015, France will have the largest Douglas fir resource in the world. A leader in the use of the Douglas fir since the 1980s, Tertu has continued to develop, using this wood in increasingly sophisticated applications: guardrails, sound barriers and protection, gangways, bridges and other crossings. Tertu Crossings Pressure-treated wood with chromium and arsenic-free preservatives Rustic gangways The design of these structures is so famous that Tertu gangways are still a talking point. The use of large round logs is a sign of original know-how, which allows for specific developments. Gangways and bridges made from wood or steel & wood combining simplicity and performances Proven feasibility for a wide range of spans. Economic and durable solutions well suited to the purpose. Lightweight constructions with great strength.

Tertu Crossings Design notes Design your project: we will direct those involved From the design of the structure gangway or bridge to its quick and easy construction, Tertu can provide all services on request. Whenever possible, we make our gangways from solid wood, giving priority to round wood to retain the structural qualities of the material and increase mechanical strength. Where the loads exceed operating limits, we assemble mixed wood & steel structures. Tertu Gangways: safety is optimized by calibrated and physically constraining "openings" which adapt to the dimensions of the equipment delivered. Tertu Bridges: the company makes an overall commitment, which can go from the start of design to the coordination of checks. Two types of crossings Tertu pedestrian gangways, solid wood up to 9 meters and mixed metal/wood beyond with an acceptable load of 450 Kg/m2. Could be equipped with normalized pesdestrian parapet (according norm XP98-405), T100 type. Short span Tertu bridges for 3.5T vehicles, designed case by case for maximum 12 m span projects. Pedestrian parapets reinforced T100 with T18 or T22. Tertu gangways and bridges comply with the standards in force. They pass the loading tests, in accordance with fascicule 61 of the CCTG (design, calculations and structural testing), with guaranteed compliance. The design notes are based on the following DDE (French Road & Infrastructures Administration fascicule: - CB 71 (design rules for wooden frameworks) - CB 61 (design and calculation of bridges and steel structures). The development of road bridges designed to support heavy loads, in accordance with standards laid down by the regulations, has led Tertu to evolve towards new assembly technologies. This experience benefits production and contributes to the performance of structures. Wood: a material for the 21 st century Its mechanical performance and ecological balance give wood a dual advantage over inert materials. Impact resistance: wood absorbs shock. In contrast to the extreme rigidity of steel and concrete, wood responds with flexibility which diffuses the shock wave instead of blocking it. Protecting the environment: wood sets itself apart. Wood stores CO2 whereas concrete and steel release it in great quantities during their production cycle, with the all too familiar consequences for the ozone layer Tertu, the world s leading manufacturer of wood & steel guardrails, has unrivalled experience with this combination of materials.
In association with design offices, Tertu is constantly looking for new uses of wood in structures and assemblies. The combination of wood and steel is also an integral part of its history and that is why Tertu is happy to offer such a combination for greater safety and improved appearance. Pedestrians gangways Moving forward To provide access with extended guardrails for pedestrians, cyclists or even horses Tertu pedestrian gangways consist of a steel structure with wooden cladding for long spans (9 m and more) or structure of large logs (dia. 280 cm) for shorter spans (up to 9m). Designed for an operating load of 450 Kg/m 2, they always come with their calculations booklet. Their guardrails with vertical bars comply with the standards concerning children (11 cm between the bars). They are supplied assembled when passage width and length do not exceed 2.12 m and 12 m respectively. In other cases, they are assembled on site by Bois de Tertu partner contractors. They are laid on concrete abutments or piers made of logs and are secured using a simple system that allows the wood to move. Easy to install and maintain. Light and strong. Attractive and durable.

In this case, they are subject to a special study concerning their transport and/or on-site fabrication. Very often, access to the location is the biggest problem for gangway projects. You should therefore check accesses for heavy goods vehicles and cranes (ground stability, electrical and telephone lines, winding access roads, etc.). Tertu gangways and bridges comply with the French standards in force. They satisfy the loading tests, in accordance with fascicule 61 of the CCTG (design, calculations and structural tests), with guaranteed compliance.

Always at the cutting edge of research, Tertu is working with the Polytechnikum in Lausanne to take its research further. New designs, new assemblies and new uses wood Gangways for light vehicles More efficient and more attractive All wood or wood & steel gangways, combining technology and simplicity. Douglas fir has always been used for the construction of bridges, some of which are more than a hundred years old and are now famous in Canada. A steel structure with a wooden cladding for long spans. Or a structure of large logs (diameter 280 cm) for shorter spans. Thanks to this experience, Tertu is designing a gangways range for light vehicles up to 3.5T. Easy to install and maintain. Lighter for the same load bearing capacity. Durability.

Pontoons and decking are very often built in protected and sensitive areas and must meet the ecological expectations of customers. They are made from wood treated with a chromium & arsenic free preservative. Pontoons and decking Paths and boarding Pontoons and decking are used for access to beaches, dunes, rivers, lakes and forest paths In comparison with gangways, pontoons and decking have short spans of not more than 4.00 m, which enables us to design much smaller structures. This naturally reduces the price of bridges and pontoons and makes installation easier. Their design is simple and they are delivered unassembled where their locations are difficult to reach by vehicles and when the geometrical configuration of the site does not allow for simple pinning. Good adaptability to site configuration. Easy and quick to install. Blend into the landscape.
