Note: this film was rescued and is in very poor condition, but is presented here because it is nonetheless fascinating. This 1960’s film demonstrates how metal walls for commercial as well as residential buildings are installed. It is presented by the National Association of Architectural Metal Manufacturers (:39) and opens with images of a bulldozer scooping up earth on a construction site (1:11). Workers are then seen within a metal refinery (1:17) as metals are reduced to their molten state (1:20). Powdery alumina is reduced to metallic aluminum in large electrolytic pots (1:32) and is cast into molds (1:54). After the metals are cast, they are sent to the rolling mill (2:02) until they are reduced into plates (2:35). The extrusion process for non-ferrous metals is then demonstrated (3:14). Piles which have been cut to stock lengths are transported to the heat treat oven (3:57). Slitting rolls further cut the sheets into specific widths (4:26) while press braking bends the architectural parts (4:40). Glass production is shown (5:26) beginning with the materials being mixed (5:33) and reduced to a molten state (5:40). The molten mixture then pours from the furnace (5:43). The glass surface is smoothed (5:55). A porcelain enamel spray can be applied to either steel or aluminum (6:23). The coated parts are then fixed and dried in the oven (6:32). Workers move the preformed heavy gauge panels onto a high capacity conveyor system (6:49). Coil sheet stock is fed into equipment for a base coating and preliminary baking (7:10). Building engineers receive feed back from the wall manufactures during preparations for production (8:11). Shop drawings are made and production schedules are set up (8:32). Insulated panels are formed (9:11). Panels with polished facings (9:58) are sent to be shaped into shallow pans (10:04) which are then filled with inorganic insulating material (10:08). Some of the patterns which can be stamped into the metals are zoomed in on (10:32). Flash welding is demonstrated which is used for window assembly (10:53). Bronzes receive chemical treatment in order to have a statuary finish (11:54) while architectural aluminum receives anodized finishes (12:04). Colored finishes are applied onto the finished metals (12:38) by a spray or a roller coating (12:43). A span of a full-sized wall which had been built for testing follows (13:14). Artificial hurricanes are created to test durability (13:14) and static pressure tests are conducted (13:21). A large wall unit is seen undergoing final assembly (13:44). Wall units then arrive at a job site (15:17) as the crew works to install the frames (15:52). Commercial type walls for low buildings arrive in preassembled units (17:44) and these units are then shown being installed (18:15). Custom type walls are looked at (18:28) as well as college and industrial buildings which often use custom wall designs (19:13). Metal walls on an industrial building are installed from the building floors which removes the necessity of exterior scaffolding (20:03). The film begins to conclude with blurry footage after a quick look at wall units designed for corners and other units which are not flat that must be installed (20:38).
