d******t

Mech is the outcome of a series of complicated production processes. These processes include timber drying, door fame manufacturing, cutting, sanding, carving, painting or laminating. The speed of this product is infinitely variable

g******b

Mech is made of high-quality timber. Its door rail, heart board, edge materials are all sourced in line with high quality, for example, any material contains insect attack, cupping, knot, or rupture will not be adopted. Its operation is safe with no heat, flame or spark risk

m******u

Adopting cutting-edge technologies, Mech is manufactured to meet the Energy Labelling Scheme. It has been recognized by the Mandatory Energy Efficiency Labelling Scheme (MEELS) and Voluntary Energy Efficiency Labelling Scheme (VEELS). The speed of this product can be adjusted steplessly

u******v

Mech is a luxury to enjoy every day and night. Using time-honored techniques and crafted of the finest materials, it is manufactured in our own factory in China. The product combines principles of simple operation with rugged construction

i******v

The production of Mech is rigorous. Along with the materials that furnish the look and feel of a building, technologies applied are also highly demanded. It has flexibility without the use of unloaders or bypass valves

o******y

This product has a rigid skeleton. Its steel members are connected via welding, rather than nails that are used in the timber/wood industry for example, this provides a much stronger and sustainable connection. It helps save costs and prevent contamination
