Each type of industrial aluminum profile has corresponding connectors, so their connection methods are also different. There are various types of connectors for assembling industrial aluminum profile frames, which can be divided into internal connectors and external connectors. External connectors include external corner pieces, bolts, nuts, fasteners, etc. External connections do not require any processing of aluminum profiles, simply tighten and fix them directly with bolts and nuts. There are many types of built-in connectors, mainly including aluminum alloy groove bar connectors, corner groove connectors, and whistle connectors. Slot bar connectors are usually used to connect two aluminum profiles in a straight line. The aluminum alloy slot bar is embedded in the groove of the industrial aluminum profile and locked with a locking bolt. Generally, both sides of the aluminum profile are required to be embedded with the slot bar. The corner slot connector is similar to the external corner component, but its feature is that it is embedded inside the groove of the aluminum profile. Our aluminum connectors are used 6000series aluminum in Metals And Alloys, which is use the surface treatment of powder coat paint. and we provide customization services like cnc aluminum, custom aluminum extrusions, casting profiles and die cast metal according to your drawing.
