From my earlier search, Grade A and B wood are similar, bit Grade B tone have much higher variety, so for light lacquer is better use Grade A. Grain wise both the same.
But from experience, the custom made wooden door you need to let it age, else you may experience crack (depend door patten design). Custom made can cost around RM 44++/sqft for Grade B, and RM 55++/sqft for Grade A.
Paint wise, Mine from old Sifu is RM 280 (or was it 350) can't recall. They don't call it paint, the term they use is stain. Painting door will cover the grain.
Wooden DoorsWent in search of wooden doors.
Visited 5 shops.
Below are a few points I've got.
I may be wrong, feel free to correct me.
Generally solid wooden doors are graded in 3 main categories.
A, B and C.
A- Very nice and relatively even wood grain / lines.
Can go for light colour varnish / shellec - to show off the nice grain / natural pattern
B- Medium quality wood grain / lines
Either dark colour shellec or solid paint - to hide the unevenness
C- Lower quality range usually mixed wood.
Solid paint only is recommended - hide everything
Wood for the mid to high range can be Nyatoh, Meranti, Merpauh..
Standard size is 33 6/8" X 83". The width is the same but the length is usuallu needed to be cut to suit your door frame.
The cost:-The price I've encountered is verrryyy varied.
Generally
Door + Installation + Painting + Lock
I concentrated on Nyatoh B and Merpauh
Door - RM 250 to 380 to 430 / pc
Install - RM120 to 150 to 200
Paint - RM100 to 200
Lock - RM20 - RM 200 or more
Some even charge transport seperately.
For narrower doors, it is not so easy to find so quite pricey for wooden doors.
Another option is Plywood doors.
It is not solid but cheap and has very modern pattern.
1 plywood door RM 350-380 include instalattion.
