2 -2SYSTEM DESCRIPTION The products in the ST range are folded or shaped sheets or plates in pre-lacquered galvanized steel or stainless steel wih are fixed by their longitudinal edging. They are characterized by their flat appearance and by the absence of visible fastenings after installation. (technical drawings nb. 15 to 20) These shapes exist with different trimmings conditioned by the geometry of their longitudinal adges, influencing the appearance and arrangement possibilities of the longitudinal junctions, generally vertical, or horizontal, or possibly oblique. This cladding is designed for vertical facades of buildings that are public or private, industrial, commercial of for dwellings, new constructions or buildnigs undergoing renovation.(technical drawings nb. 21&22 and 32&33) The products in the ST range are used for the exterior cladding of building walls using the applied cladding technique with ventilation airspace. TECHNICAL CHARACTERISTICS Manufacture by bending (technical drawings nb. 1 to 14) ST product Useful width Nominal hight Thickness (mm) ST ST ,5 ST ST ,5 Length Bonded counter-face None 1000 to to 4000 None Steel interior with min. 0.5mm coating.

3 -3FINISH ELEMENTS The finish elements are manufactued from the same plate (same thickness, same quality of material) as ST panels in a maximum length of 6.00 m.. Acroterion crown (technical drawings nb. 23 to 25 and 34 to 36). Low guards, etc (technical drawings nb.26 to 28 and 37 to 39). Window frames. Outside and inside corners (technical drawings nb. 29 to 31 and 40 to 42). Divisors IMPLEMENTATION The products of the ST range are intended to be installed on walls rails according to the professional rules for manufacture and implementation of metallic siding. The system is to be installed on a ruled secondary frame allowing a ventilated sheet of air between the panel and the support wall or thermal insulation. This secondary frame is to satisfy the requirements of C.S.T.B. n 3194 January-February 2000 «General conditions of design and implementation of the metal frame and thermal unsulation of offset siding.» The subframe wich serves as a support for ST cladding is an understakin in itself and is not an integral part of the ST procedure. The subframe conditions the final result, particularly with regard to the appearance of the cladding. A subframe is systematically required, including in the case of double-skin cladding with metallic plates on the interior skin. It serves as a support and a means to fasten the cladding. PARTICULAR POINTS REGARDING SUBFRAME The flatness, alignment and poise of the frontage walls or the main frames of buildings are generally not good enough to achieve the desired effect without adjustment of the subframe. The subframe and its hanging devices must be sufficiently strong to transmit the cladding loads. The bending factor to be respected is 1/200 in normal wind conditions. A framework design that minimized the building's strain effects and the thermal dimensional variations of the cladding is recommended. The products of the ST range do not add ot the overall stability of buildings. For aesthetic considerations it is advised to limit spans to 1,5m for the ST900 and to 2m for the other blades. The installation and the attachment of the ST blades are made on metal ribbans of following characteristics:. the width of support is of minimum 40mm.. the thickness of section of secondary frame has to allow to obtain that the plates must be fixed to ensure a minimum characteristic strength of 300 dan. ORGANIZATION The PMA company is the product manufacturer and does not install the product. ST panels are to be installed by contractors having the required professional qualifications. Design and studes prior to executing the facade are not incumbent on the maker PMA nor on the distributor companies. On request, PMA can provide technical assistance. The purpose of the present specification is not to give details on all points of implementation but to state the main technical definitions of the panels and their particular characteristics. To help in the study of the facades, it is complemented in the appendix with particular design suggestions and finishing elements.

4 -4HANDLING, UNDLOADING AND STORAGE Handling operations and carried out in consideration fo the particular features of the products. They are to be handled vertically on edge. The panels are stored in bundles, slightly inclined in the longitudinal direction on a flat surface without stacking more than two packages. Storage time on the work site is to be reduced ot the minimum. The essential precaution consists in avoiding water from entering by runoff or condensation between the panels. Store sheltered from sunlight. Metallic facades have to be normally maintained in accordance with the prescriptions of the Professional Rules for Mettalic Siding (article exterior maintenance). Although naturally cleanable by runoff of rainwater, if needed, they can be cleaned periodically with household detergent, without chlorine added, with no use of abrasive or solvent, followed by rinsing with fresh water. Maintenance notably consists of:. Eliminating various vegetation (such as moss) and any incompatible matter that might be deposited on the facing surface.. Repair of any localized degradation as soon as detected, such as incipient corrosion caused, for example, by exterior deterioration actions. CONDITIONNING AND TRANSPORT A delivery note is glued on each package stating: Customer order reference Batch reference Customer name Type of product Facing thickness Bundle content (number and length) Color reference of pre-coated plates. The weight of thebundles may in no case exceed 2.5 tons. Products of ST range and their accessories are to be transported under conditions that preserve the integrity of the characteristics (shimmed up packages, carefully stacked and strapped, tarpaulin-covered trucks). TECHNICAL DRAWINGS Following technical drawings are examples of processing of the singular points of installation the ST procuts range. Any other solutions can be envisaged and studied by the contractors by respecting the specificities of the product. The specifications for the use of the ST products range are validated by SOCOTEC within the framework of technical survey nb. GX 4335 (published Dec. 1999) available on inquiry with PMA.
