Plating
Concrete screws normally are plated in zinc with yellow or blue or
white color , and sometimes dacromet for applications in heavy
corrosion surroundings like sea .
Zinc
The most popular plating for the most products , maks parts are
bright and smooth and resistant corrosion
Dacromet
Grey color with High corrosion resistance , no hydrogen
embrittlement , heat resistance , easy to plated more ,
eco-friendly etc
Materials
Carbon steel with model 1018 , 1022 , 1035 , 1045 , SCM 435 and
40CRO
Stainless steel with model SUS 201 , SUS303 , SUS 304 ,SUS 316 ,
SUS 416 ,SUS 430 and SUS 420 .
Applications
Concrete screws are used for buildings like window frame , door etc
that into concrete material .
