GENERAL SPECIFICATIONS FOR

BUILDING CONSTRUCTION

DIVISION 05 : METALS



Foreword

The internationally recognized framework known as “Masterformat” released by the Construction

Specifications Institute (CSI) has been adopted in order to organize the sorting and numbering in the new

edition of the specifications in a manner that insures the easy flow and exchange of information among

specialists and the community of the building industry at large. The new edition involves 12 main

divisions. These divisions are:

Division 01: General Requirements

Division 02: Site work

Division 03: Concrete

Division 04: Masonry

Division 05: Metals

Division 06: Wood and Plastics

Division 07: Thermal and Moisture Protection

Division 08: Doors and Windows

Division 09: Finishes

Division 14: Conveying Systems

Division 15: Mechanical

Division 16: Electrical

Each Division comprises a number of related Sections. For example: Division 08 includes eight sections.

They are:

08100 Doors and Frames

08200 Wooden and Plastic Doors

08300 Special Doors

08400 Entrances and Storefronts

08500 Metal Windows

08600 Wooden and Plastic Windows

08700 Hardware

08800 Glazing

Further, each Section incorporates seven Parts as follows:

Part 1: General: This is mainly concerned with the references, quality control, submittals, programs,

and maintenance.

Part 2: Products: This gives a breakdown of material used in addition to their properties and place of

installation.



Part 3: Execution: The most significant items in this Part are the execution and installation of the

works, field quality control, as well as cleaning and protection methods.

Part 4: Methods of Measurement: This indicates the measurement units and the measuring methods

that shall be used for the Bills of Quantities.

Part 5: Basis of Payment: This indicates the work that shall be completed for each item of the Bills of

Quantities. It also indicates the ancillary works to be included in the unit rate.

Part 6: Annex: Tables and Figures: Those relevant to the individual Section.

1 03 Definitions 1 03 01 Technical Terms

Austenitic stainless steel - stable at temperatures above 800 deg C Brass - an alloy of copper and zinc, containing between 5 and 40 %

zinc Bronze - basically an alloy of copper and tin, additional elements may

be added for specific properties Cast iron - cast iron is an alloy of mainly iron, carbon and silicon. The

carbon contents are usually between 2,5 and 4 %. Electroplating - the electrodeposition of an adherent metallic coating

upon an electrode for the purpose of securing a surface with properties or dimensions different from those of the basis metal

Ferritic stainless steel - stable at temperatures up to about 800 deg C; the most resistant and generally used in building contains about 17 % chromium

Martensitic stainless steel - ferritic steel with a higher carbon content, which has been rapidly cooled from above a critical temperature and so becomes very hard, yet has a low corrosion resistance

Stainless steel - generally there are three different types of stainless steels: martensitic, ferritic and austenitic; the last one is mostly used for architectural and engineering purposes; a standard quality contains 18 % chromium and 8 % nickel (known as 18-8); the higher quality contains 18 % chromium, 10 % nickel and 3 % molybdenum (known as 18-10-3)

Steel - a material with iron as the predominant element, having a carbon content generally less than 2 % and containing other elements. A limited number of chromium steels may have more than 2 % carbon, but 2 % is the usual dividing line between steel and cast iron.

Annex: Specific Information 7 01 Zinc-Coating Electrolytic zinc-coating for steel sheets is applied in thickness from 1 to 15

micrometer (ISO 5002). This type of corrosion protection is not intended for outdoor use without additional treatment.

Continuous hot-dip galvanized coating for steel sheet (ISO 3575) is measured in g/m2. Coating designations are as follows: 100/180/275/350/450/600/700. Designation 100 means 100 g/m2 coating mass. 100 = G33 (American standard designation) 180 = G60 " 275 = G90 "

Requirements for hot-dip galvanized coating for fabricated ferrous products acc. to ISO 1461 are:

Coating mass: min. 450 g/m2 for steel > 5 mm " min. 300 g/m2 for steel < 1 mm " for steel > 1 < 5 mm: no requirement in Standard, needs to be fixed individually.
