BENCH 0020-303A
0020-303A
The bench is made of cast iron, metal and wooden elements. It has maximum dimensions: length 186 cm, width 60 cm and height 78 cm.
The seat frame consists of 2 side sections, made of solid cast iron (cast iron), shaped in a traditional design with dense helical shapes. Each side section has a maximum thickness of 4 cm.
These lateral sections are connected by means of cast iron horizontal cross bars 1 / 2¨, two at the seat and one at the top of the back, with a spiral end and a safety nut 3/8 ″ X70. They are 178 cm long.
For easier assembly of the seat, but also for aesthetic reasons inside each side cast iron section there are special sockets (ten in each section) for the wooden beams, with dimensions similar to those of the wood (6×4,5 cm) and depth 2 from.
The seat consists of ten (10) 6×4.5 cm rectangular wooden beams with rounded edges and a length of 180 cm curved. This curve results from a suitable beam arrangement to create a seating area in accordance with the rules of ergonomics.
Legs of the seat have a secure anti-theft mechanism on their lower legs to prevent them from moving.

TIMBER
The wood used is composite non-stick Swedish pine timber, in accordance with EN 351. It is manufactured with special compound (welding of wood) in different sections depending on the intended use.
COMPOSITE wood is 40% stronger than whole wood. It has a strength of 360 kp / m2 and a specific weight of about 480 kg / m3.
It contains about 15% moisture
Contains minimal juices (resin) compared to other pine family trees in other countries (weather in northern Sweden up to -25 ° C)
It has a thermal conductivity of s = 0.10 Kcal / Mho and sound insulation 3.5 times greater than concrete or bricks of equal thickness.
It has antimagnetic properties and is a poor conductor of electricity
It is resistant to fire and is classified in categories F30 and F60 (by DIN 4120) according to its cross-section.
When the outer part of the cross-section burns, its interior protects and retains its strength.
It is processed just like commercial wood
It retains its shape and distorts or creates minimal fractures
Annual wood rings are usually perpendicular to the long side of the cross-section with a significant increase in the mechanical strength of this surface when applied to floors.
All corners of the wood are planed to a radial of 5 mm minimum.
The wooden parts of the living room after being properly treated (rubbing, grinding, stocking) are coated with 2 layers of water-soluble paint and 1 layer of protective wax.
Seats are provided with a sufficient number of plugs to attach them to the concrete floor.
The compact cast iron of the living room frame consists of: 3.5% carbon C, 1.5% silicon Si, 1.0% manganese Mn, 0.10% phosphorus P, 0.12% sulfur.
METALLIC ELEMENTS
The metallic elements used in the manufacture of the equipment (screws, connectors, etc.) are made of metals either thermo-galvanized or electro-galvanized, where the surface preparation has been preceded by sandblasting or stainless steel. The dimensions and cross-sections of the metallic elements are sufficient to accommodate (with an appropriate safety factor) the loads for which they have been designed to withstand corrosion and adverse weather conditions.
PAINTS
The varnishes and paints used to paint the wood are specially designed for the climate of our country and are absolutely harmless to the users (they do not contain lead, chromium, cadmium or other heavy metals) and give high strength to our constructions.
All production work processes for the processing of raw materials are carried out according to
The ISO9001: 2015 quality system
The environmental management system ISO14001: 2015
