GENERALS
1.1
COMPOSITION AND USE
All the wall panels from Metecno are composite panels, formed by two metal sheets linked by a layer of insulating material,
which can be manufactured upon request:
• with combined insulation
• with mineralwool
• with polyurethane foam

Rocksteel Wall
Superwall HF
H-Wall 8M
H-Wall 10M
Monowall A-B / B-B
Superwall ML
H-Wall 8P
H-Wall 10P
When the panel is laid horizontally, no secondary purlin structures (wall stringers and secondary columns) are necessary,
since panels are directly fixed to the main columns.
The shape of the panel longitudinal joint is such as to house the fastening screw, when using douple span or multi span.
wich is then hidden inside, making panel more pleasant and elegant looking
In addition to the economic benefits for the structure costs, this solution is an
innovative architectural alternative. (only for panel type: Superwall ML / HF ; H-Wall 8P / 8M)
Due to its geometrical configuration, the panel may also be assembled in a vertical wall position in the presence of the
secondary purlin structures.
1.2
STANDARD SIZE
Panels are manufactured in 1000 mm wide modules, their length depends
on the specific design requirements and the feasibility of the manufacturing factory. Please request for that.

HANDLING AND STORAGE
Package handling and storage is a very delicate phase, in which panels can get damaged. For this reason, a label with the
following instructions is applied to each package:
WARNING !
Carefully follow these
handling and storage instructions
Sling the package by using a rocker arm and min. 200 mm-wide nylon
belts. Insert min. 200 mm-wide wooden boards between the package
and the belts. The wooden boards will have to be approximately 2 cm
longer than the package width.
Do not store more than three packages one on top of another, and place
spacers or boards between them.

Place the package on a flat and rigid surface, and position 50 mm-thick
and 200 mm- wide polystyrene spacers or wooden boards at max. 1 m
intervals. Panels will have to be stored slightly sloping in order to help
possible condensation flow and to prevent backwater.

Check that the storage has been carried out according to the directions in chapter 2.
Check that the panel support structures are level.
Position the packages of panels near the points of use.
Prepare a fixed or cradle scaffold, according to the working height, 30/40 cm far from the external edge of the main
columns and comply with the rules on safety in the workplace.
Control that all workers are equipped with individual safety equipment according to current regulations.
Prepare all the power supply lines for tools according to current regulations.
Prepare the panel lifting vehicles.
In addition to the traditional scaffolding, when assembling wall panels horizontally, automatic scaffolds with platform
can be profitably used. These platforms may be either the type with masts starting from the ground or the selfpropelled type with telescopic arms.
4.2
PREPARING PANELS
4.2.1
Before the assembly, the polyethylene protecting film must be taken away from the entire panel. Thoroughly check that no
traces of residual glue of the protecting film are left on the surface. In case, remove them using a detergent in a waterbased solution.
4.2.2
If the panel surface shows clear damages in the sheet, set the panel aside and use it when undersizes are required.

4.3.2
When panels are assembled horizontally, the purpose of the base flashing is draining the water flowing along the façade
(Figure 6). In order to guarantee that the wall is perfectly horizontal, the base substructure (tube) must be positioned using
the traditional floor control level. Once the base flashing and/or, if required, also the internal flashing is assembled (Figur e
6), install the U-shaped zinc-plated steel profile (Figure 6a) on top of the above mentioned base substructure, which is
suitable to house and block the panel without using the screw (Figure 6a).

4.3.8
When the wall is higher than 5 m, we suggest you to proceed simultaneously on all sections forming the building wall by
assembling 4-5 panels for each section, so that you can always monitor the horizontal level of the panels of the various
sections (Figure 13).

LIFTING PANELS
USEFUL CONSIDERATIONS
®
In the assembly stage of the Metecno wall panels, especially
when they are handled along the wall, considering their
horizontal size, special lifting devices can be used, like:
5.1
a suitably sized device with clamps, which in its turn is held by
a lifting device (Figure 29)
5.2
one of the most innovative lifting tools is a retaining jig with
pneumatik air sucker (Figure 30)
Steel rope
Holding ring

6.
CUTTING PANELS
6.1
If panels need to be cut to make openings or passages, proceed as follows (Figure 31):
• Protect the surface to be cut with adhesive tape.
• Draw the cut to be made on the tape using a felt-tip pen.
• Cut using a hack sawing machine.
• Clean the surface from the shavings formed during the cutting, because they can cause corrosion over time.
• Remove the adhesive tape.

PANEL MAINTENANCE
8.1
For the good panel maintenance, two phases must be distinguished:
• First phase: regards the time necessary to assemble the panels.
• Second phase: regards the use of the building, to which the panels have been assembled.
In the first phase, in order to maintain panels undamaged, you should take care of what follows:
• the handling during the unloading operations from vehicles must be carried out with suitable means and appropriate
protections, in order to prevent panels from being indented or scratched.
• the handling during the removal of the protective film and the distribution near the works. In this stage, we always
suggest that the panel and sections are controlled to remove any excess of the insulating material for the benefit of the
perfect execution of the panel coupling joint.
• the lifting operations near walls, to be carried out with suitable means and safety systems for the staff.
• the assembly stages, taking particular care to the fastening operations, immediately removing all the shavings caused
by drilling from the panel surface. In order to insert screws and avoid indentations to the panel, use screwdrivers that
are equipped with a depth limiting device.
• when, during the distribution of panels, stains or deformations (indentations) that cannot be easily fixed are found,
avoid to assemble such panels and set them aside for use as undersize elements, where possible.
8.2
If the above-mentioned recommendations are truly complied with, they guarantee the product integrity and avoid the
annoying building yard objections that very often translate into unpleasant financial costs. The second stage regards the
panel maintenance, which is the final user’s task, in order for the panels of his building to maintain their original look and
have the building look pleasant.
8.3
The consequences of a slow degradation of the pre-painted external sides are mostly originated from the contact with
aggressive substances contained in corrosive air and gaseous emissions from surrounding activities. Therefore, periodical
inspections to the panels should be planned in order to find possible corrosion; if it is found, action should be taken
immediately, starting protective cycles to stop the process. In the long run, smog deposits on painted surfaces and may
create a dirt film, and the walls will have to be cleaned with water jets.
8.4
The existing seals will have to be controlled, verifying that they are still airtight and waterproof, which otherwise may
cause deterioration. All the fastenings will have to be controlled to verify that they are still in good conditions. Any
scratches of the paint that may have been caused accidentally will have to be protected by retouching: cleaning and
painting. In case of large size dents caused by impacts, the panel will have to be replaced.
8.5
DISPOSAL
In case of yard working wastes and/or dismissal, the panel disposal shall only be entrusted with authorized
companies and carried out in compliance with the current laws in each country.

9. SAFETY INFORMATION
Each user and/or worker must be aware of all the problems connected with the assembly of these panels, and should
prepare a SAFETY PLAN in order to prevent dangerous situations.
THEREFORE, WE REMIND YOU TO STRICTLY COMPLY WITH THE REGULATIONS ON SAFETY IN WORKPLACES,
BUILDING YARDS AND EQUIPMENT SAFETY.
