Advantages and disadvantages of glulam, glulam specifications

Glued laminated wood:

Glued Laminated Timber (Glulam) is one of the three main types of engineered timber, along with wooden I-beams and laminated veneer lumber. Glulam, sometimes also called finger-jointed timber, can be coated with wood wax to prevent deformation.

Glued wood

Glulam is a wood panel made by splicing high-quality large-diameter logs. It retains the texture and beautiful appearance of natural wood, and is made with exquisite craftsmanship. The board surface is smooth, strong and easy to process, not easy to deform, low in formaldehyde, strong, and has high thermal insulation properties.

Product Standards:

A. Length and width tolerance: 0mm---5mm.

B. Uniform thickness, thickness tolerance: 0mm---+0.5mm.

C. 40mm＜lath width＜65mm. (The lath width of 15mm, 16mm, 17mm, 18mm thick boards sold on the market can reach 80-90mm wide)

D. Must be dried, moisture content: ≤12%

E. Double-sided sanding, the board surface is smooth and flat, without bark and filler.

F. Apply glue to the finger joints. The amount of glue should be large, the adhesive strength should be good, and there should be no height difference at the finger joints.

G. The fingers are connected in place, with no cracks on the board surface and ends.

Product advantages:

Glulam surpasses solid wood in both tensile and compressive strength, and also offers greater uniformity of material quality. Customized panels feature thickened cores, ensuring sufficient thickness and environmental friendliness. Their natural texture creates a sense of belonging to nature, and they are easy to process and manufacture.

Applications:

1. In terms of furniture, integrated wood is used in the furniture manufacturing industry in the form of integrated panels, integrated square materials and integrated curved materials.

(1) Integrated panels are used for large-scale components such as table panels, cabinet side panels, top and bottom panels, cabinet partitions, bottom panels and drawer bottom panels that are not exposed, and small-scale components such as drawer panels, side panels, bottom panels, and cabinet doors.

(2) Integrated square timber is used for brackets of tables and chairs, legs of cabinets and other square or circular cross-section parts.

(3) Integrated curved materials are used in curved parts such as chair frames, armrests, backrests, sofas, coffee tables, etc.

2. In the application of interior decoration, integrated wood is used as interior decoration material in the form of integrated panels and integrated square materials.

(1) Integrated panels are used for materials such as stair side panels, treads, floors and wall decoration panels.

(2) Integrated square materials are used for beams, columns, decorative columns, stair railings and decorative strips of interior doors, windows and cabinets.

How to select integrated board:

1. Check the board surface: high-quality integrated board, clear wood grain, beautiful texture, natural texture. The board surface is flat and smooth, without obvious grouting, sanding, pressure, obvious color difference, and stains;

2. Check the joints between the slats to see if there is any debonding, peeling, excessive cracks, wormholes, skin inclusions, resin channels, or decay.

3. Check the thickness: Is it full size? Are the thicknesses at both ends and in the middle consistent?
