Number of addition elements (field grid, 940 mm) .............................................................................................................
System shelter type QUATTURA with mono-pitch roof geometry, roof depth ❏ 2250 mm (Single) or ❏ 2 x 2250 mm (Twin), clearance
height 2100 ... 2300 mm. The structure is erected as a building kit system by configuring a base element together with a number
of addition elements to achieve a required length (L) for the system. Both the base element as well as addition elements are to be
designed for a field grid of 940 mm.
The roofing material is made up of aluminium elements. Roof slope is downward toward the rear at an angle of 5°. The longitudinal
field grid is 940 mm, thus providing compatibility to other system products.
The roofing material has continuous edge support from the overhang joists. The roofing has a non-positive connection to the frame
made with screws and deck strips with seals. The overhang joists are IPE sections with a 45° bevel-cut at their ends; these also have
a hole pattern along their centre-stay surfaces.
The vertical supports are hollow sections rigidly connected to the overhang joists. The flange bends necessary for this are provided
and certified. Each roof grid area has a pair of pressure rods made of round tubing positioned at an offset to the pressure rods of
the adjacent roof grid area/s. The bottom end of vertical supports are to be
❏ shackled in pit foundations at the construction site then set in concrete after assembly of the shelter's steel framework, or
❏ bolted to a suitable surface by way of rigid base plates.
The structural dimensioning of all support structure elements is carried out according to static requirements (DIN 1055). The structural
shape, cross section, building height, connections and stabilisation are to be optimised through structural and static calculations. The
entire structure is to be designed to handle a rated snow load of 0.75 kN/m2.
The manufacturer shall possess a "short-form qualification certificate" in compliance with DIN 18800, Part 7 to perform welding
work. The material used in the steel frame structure must be S 235 JRG 2C quality per DIN EN 10025 and DIN 17100, Material
No. 1.0122 and produced for hot galvanised suitability with appropriate alloying constituents (elimination of the so-called
"zinc/iron reaction").
The anchoring point of the horizontal roof beam section, the corresponding anchoring point at the top of supports as well as all
other such connections in the entire structure are to be designed with weld/screw joints such that welding work at the construction
site (which would be detrimental to corrosion protection) can be absolutely eliminated. Such a design also makes it possible to
replace individual parts or to expand existing systems with additional modules.
The clearance height, as measured from the under surface of the roof beam section shall vary between 2.10 and 2.30 m
Controlled drainage for the shelter system is provided for the roof's surface by a triangular-shaped rain gutter fastened to the rearside
of the overhang which has water-tight end caps. This rain gutter is emptied by the required number of downpipes.

The entire roof structure shall consist of industrially manufactured system components.
The award of contract is contingent upon provision of a functional sample at the premises of the tender inviting office as well as the
naming of a location where a structure equivalent (in the sense of >identical
