A question and answer article where you'll find anything you'd like to ask and learn about composite lumber. With full development of the features and advantages that this option will give you.
What is composite lumber??
Composite timber, as it has come to be called, is mainly composite multi-glued beams. The composite timber in beams is produced from many types of wood with the predominant oneEuropean fir (whitewood)and European pine (redwood). Composite wood is also produced in the form of composite welded surfaces (plates and boards), i.e. panels made of fir, pine, beech, oak, iroko, etc.
Composite lumber is produced fromsolid dryer timberwith humidity max up to 10%, after it has been preceded bycareful screening ofby removing pieces that have defects, such as large pinks, holes, cracks, blackening, cyanosis, resin pockets, etc.
Where is composite lumber used ??
We should make a necessary distinction of composite wood uses between composite wood panels and beams.
a)Beams of composite multi-glued timber (GLULAM)
Composite timber beams are mainly used in constructions (roofs, pergolas, gazebos, etc.). It is a modern building material. The composite beams,due to the long lengthswhich can also be produced of the large onevariety of cross-sections, can and reliably cover any technical requirement or architectural choice, in any project.
Advantages of composite timber beams:
a)long lengths
The lengths of the composite beams reach up to 13 or even 13.50 meters, which greatly facilitates us in every construction. By special order, composite timbers can be produced in much longer lengths, but there is a serious problem in transporting them.
b)Variety of dimensions
The usual and most common dimensions of composite timber are:
9 X 9 9 X 13 9 X 16 9 X 21
8 X 16
9 X 26 9 X 30
12 X 12 14 X 14 etc.
On request, many other dimensions can be delivered (lengths and cross sections), both in European fir wood (Scandinavia) and in pine wood (Scandinavia), in the dimensions desired by the customer. Also, by order, composite woods from iroko, niagon, meradi, etc. are delivered for special constructions.
c)Dimensional stability
Due to the production method and strict specifications, composite lumber has better characteristics than classic sawn or presawn lumber.
Composite timber has all the advantages of wood with high mechanical strength as well as great elasticity.
d)Low weight
Spruce composite wood has a specific weight of approximately 470 – 490 kg per m3. It is clearly lighter than many other materials that could alternatively be used in the same construction, such as iron, steel, concrete, etc.
e) Composite timber has andmany other advantages όπως την αντοχή που παρουσιάζει σε χημικό περιβάλλον, την ευκολία στην επεξεργασία της (κόβεται εύκολα, βιδώνεται χωρίς δυσκολία κλπ) με απλά ξυλουργικά εργαλεία, βάφεται και λουστράρεται με επιτυχία, έχει καλύτερο δείκτη αντοχής στη φωτιά σε σχέση με άλλα υλικά, έχει αυξημένη θερμομονωτική ικανότητα, αισθητική ομοιομορφία, καλύτερες αντοχές ως προς την θλίψη, την κάμψη και την στρέψη.
g)In the productionof composite woods (beams) special glues are used with increased strengths that make composite timber beams suitable for every use.
h) Tperfect final formproduct, with all surfaces planed and the four corners of each piece rounded. Product ready for use, without the need for further processing.
i)It is necessary,to separate hercomposite multi-glued timberfrom composite split timber.
Split-joint composite lumber has none of its major advantagescomposite wood gluer.The dowel is clearly inferior in quality, without the strength of the composite wood dowel. The dowel is a much more economical solution that is chosen only for its lower price.
Τα μεγάλα μήκη που μπορεί παραχθεί, λόγω του finger jonting, είναι τελικά το μόνο πλεονέκτημα της δικολητής σύνθετης ξυλείας. Η δικολητή σύνθετη ξυλεία δεν συνιστάται για σοβαρές κατασκευές με προδιαγραφές και υψηλές απαιτήσεις, γιατί η δικολητή σύνθετη ξυλεία υστερεί συνολικά σε σχέση με την πολυκολητή σύνθετη ξυλεία.
The main uses of composite multi-glued timber in the form of beams are:
. on the visible roofs of houses, hotels, restaurants, etc
. on covered terraces, loggias, canopies, etc.
. in pergolas and gazebos
. in special wooden constructions (pedestrian bridges – constructions in squares, surroundings
residential areas, hotels, parks, etc.).
. in constructions that have increased strength requirements. Composite lumber has a minimum40% greater endurancefrom solid sawn timber.
. on roofs of industrial and craft buildings, sports buildings, etc., which are required
long lengths. By using the composite timber we avoid the installation of dense
rows of columns, i.e. many columns.
. on roofs of warehouses, logistcs, prefabricated and agricultural buildings, as well
in any other structures we seek to have uniform large spans.
Our company has ready-to-deliver certified composite multi-glued timber,both in the form of beams and in the form of panel surfacesin a wide variety in many dimensions and many lengths.
The composite timber panel
The composite wood in the form of panel surfaces is mainly used in furniture (office lids, tables, shelves, kitchen counters, etc.), in carpentry constructions (indoor stairs), in the interior decoration of homes, shops, hotels, etc.
ADVANTAGES
1) large widths, usually 64 cm and 80 cm
2) long lengths, usually 4.00 m. and in some species and 6.00 m.
3) considerable variety in thicknesses, i.e. 20mm 25mm 30mm 40mm
4) excellent final form. The panels are delivered planed without defects on their surface (cracks, blackening, falling pink, cracks, etc.)
5) perfect aesthetic result
6) the possibility of constructing single surfaces in large widths up to 80cm, which is impossible to achieve in solid wood without the necessary welding of pieces by qualified carpenters
7) the panels are available in a wide variety of wood types (pine-fir-beech-oak etc.)
Standard three-ply composite timber for frames
Διατίθεται ξυλεία τρικολητή σύνθετη, κατόπιν παραγγελίας, σε ποικιλία διαστάσεων από ξύλο μεραντί, νιαγκόν,κλπ τροπικά ξύλα, που είναι κατάλληλη κυρίως για ξύλινα κουφώματα. Η διαστασιολογημένη σύνθετη ξυλεία που προορίζεται για ξύλινα εξωτερικά κουφώματα (κασώματα, μπαλκονόπορτες, μπαντζούρια κλπ), υπερτερεί σε αντοχή και ποιότητα σε σχέση με τη γνωστή μασίφ ξυλεία, γιατί έχει υποστεί ειδική επεξεργασία..
With regularity and correctnessmaintenancewith the right products, the strength and lifespan of the frame increases, regardless of the climatic conditions it is in.
The facilities of our business, despite the long lengths of composite timber that reach up to 13.50m and we have ready-to-deliver,allow us the correct and its safe storage in closed, covered storage areas.The storage of any kind of timber incovered warehousesspaces, constitutes theconditionfor the safe andsuccessful useof timber in any wooden structure. Any timber and especially composite timber, if not stored in covered closed storage areas,is degraded in qualityand its resistances are depreciated, as a result of which, among other things, its life span is reduced.
The crane trucks of our company ensure the deliveries of both composite timber and many of our other products, transporting it to the surrounding areas.
The many years of experience of the people of our business in wood and themeticulous selection of suitable and quality composite multi-glued timber, ensure our customers thesuccessful completion of their constructions.
In our business there are ready-to-deliver and everythingthe necessary decoration protection products andwood preservation, such as colored solvent impregnation varnishes, marine varnishes, water-impregnated eco-varnishes, clear eco-wood varnishes, as well as all products of the leading company of wood preservation and protection products BONDEXDenmark.
At the same time, we also have everything necessary for wood constructionmetal components, such as metal angles, split bases, slats, joists, headers, connectors, collars, wood screws, torx screws, carabiners, tile covers, combs, adjustable
