Obtain revised KS standards and KS certification! Zenfix's first-grade non-combustible DMC metal ceiling! [KS mark/non-flammable ceiling/metal ceiling material]
Hello!👋
It's Zenfix, 'Creative New Value for the Ceiling'.
KS D 7081 standard, which is applicable to metal ceiling materials, was newly revised on May 12th.
I'd like to inform you of the good news that our metal ceiling DMC and the sound absorption metal ceiling SDMC have been certified for the revised KS standard!
Before looking at the revisions.
What is KS certification?
KS (Korea Standard) is a Korean industry standard.
It is the most representative certification system in Korea. It is a national standard that defines products, testing, and manufacturing methods in all industries of Korea.
It is a kind of quality assurance document that inspects and certifies factory inspection, material control, process control, quality control, manufacturing facility management, and inspection facilities for the company's production of standardized products.
If the quality of the product is assessed and passed to a certain level, the KS mark may be marked on the product!
Let's take a look at the revised specifications one by one!
First, the d,e item has been added to the material of the original plate.
d refers to galvanized steel sheet materials and e refers to galbarium steel materials.
If you look at the comment below, it says that you should use non-combustion if you use d,e.
In other words, the ceiling of zinc and galbarium materials with KS certification means non-combustible products!
Next, if you look at the pore part of the original plate, it is divided into two types, one without holes and the other with holes.
A type without a hole means that the ceiling is not perforated.
Among Zenfix products, the non-combustible metal ceiling DMC is a type without holes.
The perforated type has a sound absorber bonded to the ceiling material, and is perforated. Zenfix's non-combustible absorption metal ceiling material SDMC is a perforated product.
The perforated ceiling material shall have a fully penetrated hole from the surface of the original plate to the rear with the acoustic material bonded to the back.
Also, the size and area of the perforated ceiling is determined.
First, the perforated area of the perforated ceiling material should be at least 20% of the finished product area.
If the size of the hole in the ceiling is normal and round, it shall be drilled steadily to a size of Φ1.0mm, and the square to a size of 1.8mm with a gap of 5mm, and the allowable difference is + 0, - 0.15mm.
Compared to other companies' perforated ceilings, Zenfix's SDMC sound absorption metal ceilings show excellent product quality with dense hole clearance as standard.
I recommend that you check the hole when you buy it because the quality of the product that doesn't fit the space or the shape of the hole is not circular.
Next is the luster.
We're following the standard of semi-gloss.
Many people prefer the subtle gloss that feels luxurious!
There's also a standard for adhesion.
The coating adhesion or coating adhesion experiment is an experiment in which the product is strictly evaluated by a recognized institution according to the standards set by the country.
As a result of requesting a proper certification authority to test Zenfix's non-combustible metal ceiling material DMC and sound absorption ceiling material SDMC, we have obtained a test report that is correct!
ZENFIX's DMC of metal ceiling material and SDMC of absorbent metal ceiling material can be used with confidence with KS-certified products due to first-class non-combustion!
Usually, government offices use KS certified products, but private levels do not specify that KS products should be used, so you can use semi-flammable DMC metal ceiling products that are cheaper!
