ZINGA

PSA Lighting Masts

PSA (Port of Singapore Authority), is the 4th largest port in the world and the second busiest after Rotterdam. ZINGA was selected to be coated on 30 lighting masts.
Each lighting mast measures 45 meters in height within minimum DFT of 120 microns.
At this moment 90% of the light masts in this harbor are protected with ZINGA . The first light masts were treated in 2002.
Being at the container area, most of the lighting masts (previously protected by hot-dip) were installed near to the sea coast and were found to be quite rusty.

Anti-slip coefficient of high strength bolts adjoining steel sections

GB 50017-2003 Code for design of steel structures
GB 50205-2001 Code for Acceptance of Construction Quality of Steel Structures

In Octobre 2005, ZINGA coated plates have been tested according GB 50017 and GB 50205 to assess the slip friction coefficient (µ) of high strength bolts adjoining steel sections.

The results demonstrate that ZINGA coated surfaces of high strenght bolts have increased friction (compared to bare steel or galvanised steel) with results of µ between 0.5 and 0.7. This is beneficial for construction.

ISO 12944 on ZINGA + Zingatarfree

ISO 12944-6: Paints and varnishes — Corrosion protection of steel structures by protective paint systems
The ISO 12944 standard is intended to assist engineers and corrosion experts in adopting best practice in corrosion protection of structural steel with coatings at new construction and repairs. ISO 12944 is progressively superseding regional standards to become a truly global benchmark in corrosion control.

The ZINGA/Zingatarfree system has been subjected to extensive testing such as water condensation
test, neutral salt spray test, chemical resistance test and water immersion test. After a prescribed exposure test (depending on respresentative environment), the coating is assessed for adhesion, blistering, rusting, cracking and flaking.

Environments are classified according corrosivity for structures in immersion:
• Im1: Clear, fresh or potable water
• Im2: Sea or brackish water (harbors with locks, jetties, offshore structures; make sure there is no stray
current)
• Im3: Soil (underground storage, iron poles)

After exposure, the coating is evaluated as H(igh), M(edium) or L(ow); reflecting in a life expectancy of:
Low: Life expectancy less than 5 years
Medium: Life expectancy between 5 and 15 years
High: Life expectancy more than 15 years

The system

ZINGA 1 x 60-80 µm DFT

+

Zingatarfree 2 x 100 µm DFT

passed the tests for Im2 and Im3 with a High Classification.

Lloyds Register Recognition

Based on reports, test certificates and documents from independent research facilities from around the world, ZINGA has been approved for use in void spaces (all internal structures except for oil tanks and ballast tanks) by Lloyd’s Register.

The Lloyd’s Register Group is a maritime classification society and an independent risk management organization providing risk assessment and mitigation services and management systems certification.

Mumbai Domestic Airport

The domestic terminals in Mumbai with the same name as its international wing are located in Santa Cruz, East. There are two domestic terminals -Terminal 1A (with an area of 28960 sqm), and Terminal 1B (with an area of 45000 sqm).

Terminal 1B was constructed by Unity Infrastructures where the Structural Consultants were M/S Mahimtura & Co.

In 2006 all steel structures including the huge curbed spans of the new airport of Mumbai Domestic Airport are coated with ZINGA and finished with a white PU.
5 years after application the structures still look as if they were treated yesterday.

The testimonial was written by the responsable of Pratibha Pipes & Structral Pvt. Ltd., the steel constructor and coatings applicator, after application.

Pacific Grain Elevator

In 1998 the company ‘Pacific Elevators LTD’ decided to refurbish their grain elevator in Vancouver.
After consulting with the consulting engineers from ‘Villholth Jensen and associates’ it was decided that ZINGA would be used on the 200 ton structure.

ZINGA was used on all the larger -non-mobile-parts of the structure.
