11.4.2.7 Welder's identification: each welder should have a special identification tag. This

tag should be non perishable. For traceability purposes every welder should sign (by imprinting) his welding work with his identification tag.

11.4.3 Tolerance in Fabrication All tolerances in fabrication, dimensions, layouts etc. shall be in accordance with

the AISC 303-05 Code of Standard Practice for Steel Buildings and Bridges. 11.5 Corrosion Protection. 11.5.1 General requirements: 11.5.1.1 Structural steel shall be protected against corrosion by Duplex system

(galvanized and painted). 11.5.1.2 Surface areas of the structural steel which have been milled and for which the

milled surfaces are to be retained without coating, shall be protected during galvanization and/or painting so that they remain without a galvanized or paint layer. Varnish shall be brushed in mill area.

11.5.1.3 Connection Areas of slip critical joints shall meet the requirements of 3.2.2(c) of

Specification for Structural Joints using ASTM A325 or A490 Bolts (2004). Connection areas of painted structures shall be masked after priming before the

intermediate and top painting.


ZC-4341 rev 2013 08 22 B - 20

11.5.1.4 In any case, fabricator shall remove the masking in the shop. If "No Paint Areas" become soiled or painted, Contractor will remove any foreign

matter at its own expense. 11.5.2 Painting Systems: 11.5.2.1 The colour of the top coat will be decided upon at a later stage, in accordance

with RAL color scale. 11.5.2.2 Hot-dip galvanized structures shall be painted according to I.E.C.

Spec/Procedure CL-716/1600/99 Issue 5 (Supplement 5.1.2 to the Specification). 11.5.2.3 Non-Galvanized structures shall be painted according to Specification 217-

000093-2011 (Supplement 5.1.1 to the Specification). 11.5.3 Scope of Galvanization: 11.5.3.1 All Structural Steel Members that can be inserted in a galvanization tube shall be

hot-dip galvanized according to Israeli Standard 918, latest edition (or equivalent standard, as approved by the Purchaser)

11.5.3.2 The corrosion protection of all Structural Steel Members that cannot be inserted

in a galvanization tube shall be subject to Purchaser’s approval. 11.5.4 Detailed Galvanization requirements. 11.5.4.1 The shop drawing designer shall design the elements to be galvanized, while

considering the peculiarities of the galvanized steel structure and ensuring that:

a. Holes to drain the excessive liquid zinc are provided. b. Fillet weld are continuous.

11.5.4.2 The general and detailed conditions for the preparation, galvanization and testing

of the galvanic coating shall be as specified in, and according to Israeli Standard 918, "Hot Dip Zinc Coatings on Steel and Cast Iron Products", latest edition, and to the following mandatory requirements:


ZC-4341 rev 2013 08 22 B - 21

11.5.4.2.1 All Galvanized Structural Members shall pass 100% visual examination of the coating quality. Items with defective coatings shall be repaired by Contractor according to a method approved by the Purchaser.

Non-acceptable defects are: bare spots, flux, rust, rust to welds, brittle areas.

Dripping and sharp edges are non-acceptable if they interfere with the intended use of the member.

11.5.4.2.2 Galvanized steel members shall be stored with adequate ventilation between

each member: Each member shall be separated from the other by small steel or galvanized steel spacers. Members shall be stored vertically if possible. If stored in the horizontal direction, the members shall be tilted at a small angle to the horizontal (recommended 5 degrees) so that water cannot accumulate on the surface.

11.5.4.2.3 Handling of galvanized steel shall be done with care to avoid mechanical damage

to coating. 11.5.4.2.4 Quality Control for Galvanizing The galvanizer will have a formal and documented quality system, which includes

quality control department. The quality system shall encompass at least the following items:

a. Calibrated equipment to measure zinc coating thickness. b. A procedure for identifying, tracing and recording all coated items

including a system for identifying and inspecting status of the galvanized items, either coated and tested singly or coated and tested as a batch.

c. Procedures or instructions for rejection and acceptance of coating

quality. d. Written limits on the composition of the cleaners, wash solution and

zinc bath and a system for their control and inspection. e. Written instructions and inspection forms for the acceptability of

cleaned surfaces.


ZC-4341 rev 2013 08 22 B - 22

f. Written instructions and inspection forms for the acceptability of

visually inspected surfaces. g. Procedures and/or Instructions for in process control of the whole

galvanizing process. h. Written instructions and inspection forms for the acceptability of

coatings which have undergone thickness tests. i. Temperature control of the bath and calibration of the control

instruments. j. Inspection criteria for the suitability of welded assemblies and sub-

assemblies for galvanizing, and instructions for the clients. 11.5.4.2.5 Specification for Repair of Defects in Galvanized Coatings All galvanized parts shall be inspected after cooling to ambient temperature.

Rejected parts shall be cleaned and re-coated as follows:

a. Drippings, sharp edges, excess zinc droplets, etc., shall be removed by means of grinders or any other suitable tool, when their presence interferes with the intended use of the component.

b. Spots of flux, dirt, soot or other impurities shall be cleaned by wire

brushing. c. The weld areas of Zinc coated parts which are subsequently welded

shall be cleaned by wire brushing. d. Scratches and similar linear imperfections shall be cleaned by wire

brushing. e. Uncoated surfaces are unacceptable, and shall not be repaired.

Contractor shall re-coat such surfaces at no extra cost to Purchaser. - F I N A L -
