Because of their established relationships with foundries and mills, these distributors can make sure that high quality parts are available from stock for immediate shipment. And, by providing data on the structural properties of this material, the architect is able to design in conformance with national and local code requirements. ©2013 ∙ Table of Contents Slide 7of 70 • About the Instructor • About the Sponsor • Ask an Expert The Benefits of Purchasing Stock Components There are numerous reasons why stock components are commonly used and/or specified by architects, contractors, fabricators, and building project teams. • Large quantities available “off the shelf”. • Quality products meet quality control. • Products are designed and engineered to meet current codes. • Complete systems aid in ease of design and installation (by an experienced miscellaneous metal fabricator). • Installation drawings and details are supplied for all products . • Cost advantages to purchasing prefabricated and pre‐ engineered items . ©2013 ∙ Table of Contents Slide 8of 70 • About the Instructor • About the Sponsor • Ask an Expert Packing and Handling A high quality prepared surface is important for the best visual properties, architectural performance, and long‐term durability. For these reasons, it is important that the selected supplier takes the measures listed below. Customers should expect: In the warehouse: • Suppliers should use paper leaving to protect metal surfaces. • Stacked bundles are wrapped and crated for general protection. For transport: • Heavy tri‐wall bundle wrapping protects the individual bar stock . • Steel strapping eliminates the possibility of bending. • Paper wrapping protects the surface from scratches and deflection. ©2013 ∙ Table of Contents Slide 9of 70 • About the Instructor • About the Sponsor • Ask an Expert Environmental Awareness Metals: Recycled and Recyclable. The ever‐growing importance of protecting the environment and reducing waste extends to the metal industry as well. Architectural metals are largely composed of recycled material. Information on the recycled content of the material should be available for those that require LEED® certification. Packing: Eco‐Conscious Packing. Using old newspapers as packing material, reusing storage boxes and bins, and recycling unused business forms into memo pads are examples of the small ways a business can continue to keep the environment in mind. ©2013 ∙ Table of Contents Slide 10 of 70 • About the Instructor • About the Sponsor • Ask an Expert Metal Alloys for Architectural Metal Work A number of common metal alloys are described as architectural metal. Each offers unique performance properties and visual characteristics, and is suitable for specific applications. Some of the most common architectural metal alloys include: • Aluminum: 6063‐T52, 6063‐T832, 6061‐T6. • Bronze: Alloy C38500. • Stainless Steel: Alloy 304. • Nickel‐Silver: Alloy C79800. • Steel: Alloy C1010. • Malleable Iron. • Cast Iron. ©2013 ∙ Table of Contents Slide 11 of 70 • About the Instructor • About the Sponsor • Ask an Expert Metal Alloy Interactions When specifying a metal type for a job, the specifier should be aware of any possible interactions a metal will have with another metal, between metals and cement/lime mortar, and between metals and the environment. • Aluminum should be coated with either a mechanical or chemical coating and should not be left unfinished against cement/lime mortar. • Bronze/nickel‐silver left untreated will develop a patina, e.g. the Statue of Liberty. The speed at which the metals will patina is dependent on both the bronze alloy and the environment. • Stainless steel is not affected by contact with other metals or by the environment. • Steel will corrode if not properly protected by paint or other coatings. ©2013 ∙ Table of Contents Slide 12 of 70 • About the Instructor • About the Sponsor • Ask an Expert Types of Metal Finishes The finishes that are most commonly used on architectural metals can be classified into the following types: • Mill Finishes: These are finishes applied by a basic rolling mill, the extrusion press, or a casting mold. • Mechanical Finishes: These finishes are applied by the fabricator, and are the result of physically affecting the surface of the metal by some mechanical means. • Chemical Finishes: These finishes (usually a pre‐finish) are applied by the fabricator, and they may or may not have a physical effect upon the surface of the metal. • Coatings: These finishes are either formed by the metal itself by a chemical or electrical conversion process, or formed by application of added material applied by the fabricator or specialist. NAAMM/NOMMA 500‐06, Metal Finishes Manual for Architectural and Metal Products is an excellent reference for metal finishes and can be found here: http://www.naamm.org/amp/amp_technical_literature.aspx Accessed May 2013. ©2013 ∙ Table of Contents Slide 13 of 70 • About the Instructor • About the Sponsor • Ask an Expert Types of Metal Finishes The following table references the previous two slides and further matches metals with their finishing options.
