Rustic gangways

The design of these structuresis so famous that Tertu gangwaysare still a talking point.The use of large round logs is a signof original know-how, which allowsfor specific developments.

Douglas fir:the speciewith a big heart

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

Tertu’s international development has

enabled us to acquire expertise in

deployment in wide-ranging geographical

environments.

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.

Motorway

Tertu Crossings

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.

Design your project:we will direct those involved

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.

Wood:a material for the 21st century

Designnotes

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).

Two types of crossings

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.

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.

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.

Moving forward

To provide access with extended guardrailsfor pedestrians, cyclists or even horses

• Easy to install and maintain.

• Light and strong.

• Attractive and durable.

• Advice and coordination

to complete the project together.

Pedestrians gangways

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/m2, 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.

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.

All gangways can be delivered

for openings of more than

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.).

standards in force. They satisfy

Gangways for light vehicles

Douglas fir has always been used for the

are more than a hundred years old and

are now famous in Canada.

A steel structure with a wooden cladding

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

Pathsand boardingPontoons and decking are usedfor access to beaches, dunes, rivers, lakesand forest paths

• Good adaptability to site configuration.

• Easy and quick to install.

• Blend into the landscape.

Pontoons and decking

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.

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.
