FASTENER COATING
Cadmium offers excellent corrosion protection, particularly in
harsh environments such as marine or aerospace applications.
The cadmium layer provides good wear resistance,
contributing to the bolt’s longevity and performance.
In case of damage, cadmium can act as a sacrificial
coating, corroding in place of the base metal, thus
protecting it.

The zinc layer acts as a barrier, protecting the
underlying metal from corrosion caused by
exposure to moisture, air, and other environmental
elements.
Zinc plating is relatively cost-effectivecompared
to some other coating methods, making it a popular
choice for various applications.
Zinc plating can provide a n appealing finish and
can be further treated for improved aesthetics or
additional protection.
One layer ofDACROMET® and GEOMET® has demonstrated
0% red rust after 1000 hours of Salt Spray Test hours (tested
against ASTM B117).This performance exceeds that of Electro
– Galvanizing, Hot Dip Galvanizing and Mechanical Galvanizing.
The corrosion resistance capability can be further enhanced by
applying multiple layers of coating. Alternatively, DACROMET®
and GEOMET® can be trusted as a base coat to be applied with
other top coats. The inorganic base coat protects the substrate
from any chemical reactions and the overall corrosion resistance
will be increased exponentially.
“Hydrogen embrittlement may cause premature failure of parts which are heat
treated
or cold worked to a surface hardness of 320HV
and above or property
class 8.8 or above.” BS 7371-6
AT LEAST 1000 HOURS OF SALT SPRAY TEST

SUPERIOR ALTERNATIVE TO HDG, DACROMET® and GEOMET® coated fasteners have demonstrated superior corrosion resistance
performance compared to HDG ones. When we performed salt spray test as per ASTM B117 on both types of bolts, HDG bolts began
to have 10% white rust at approximately 48 hours whereas DACROMET® and GEOMET® coated bolts are still in exhibiting 0% white
rust and red rust after 1000 hours of salt spray test.
In addition, hot dipped galvanizing requires a minimum coating thickness of 36 microns. To compensate for the fit between bolts and
nuts, ASTM A153 allows the nuts or tapped holes to be tapped to meet over-tapping allowances. DACROMET® and GEOMET® do not
require any reworks as the average coating is only 8-10 microns.
XYLAN COATING
Fluorocarbon coating : Superior Corrosion Resistance
Xylan coating provides outstanding protection against
corrosion in various environments. This fluoropolyme
-based coating shields bolts and nuts from moisture,
chemicals, and corrosive elements, ensuring prolonged
durability even in harsh conditions.
Meterials that coated with Xylan coating are often considered suitable
for use in petrochemical applications. The Xylan coating offers several
advantageous properties that are beneficial in such environments:

TUNNEL SEGMENT ACCESSORIES &
RAIL / TRACK FASTENING SYSTEM
Since the construction of the first MRT line in Singapore in the 1980s, we have manufactured and supplied accessories for the tunnel & rail projects. Our rail fastening systems, tunnel segment lifting systems and tunnel segment linking systems are used in various tunnel & rail projects throughout Southeast Asia.
