Choosing suitable aluminum profile connectors requires a comprehensive judgment based on profile specifications, load-bearing requirements, connection scenarios, and aesthetic requirements. The core principle is to balance strength, aesthetics, and ease of installation. Specific selection methods are as follows:
Matching Basic Specifications
Differentiating Between National Standard and European Standard Profiles
European standard profiles have T-slots, requiring the selection of corresponding European standard series accessories; national standard profiles have rectangular slots, requiring the selection of national standard series accessories; corner fittings, corner brackets, and other accessories are universally compatible with both national and European standards, only needing to match the profile specifications.
Matching Slot Width and Dimensions
Accessory specifications must match the profile specifications. For example, 40 series aluminum profiles require 40 series accessories; profiles with a 6mm slot width require accessories of the corresponding width; bolt diameter must be less than or equal to the profile slot width; and bolt length must match the profile thickness.
Choosing the Right Connection Based on Connection Scenarios and Needs
90° Right Angle Connection (Most Commonly Used)
For those prioritizing aesthetics and appearance: Choose built-in corner groove connectors/anchor connectors, hidden inside the profile for a cleaner look.

For those prioritizing strength and ease of installation: Choose external corner brackets/fittings. No pre-drilling is required; direct fixing is sufficient. This provides higher connection strength, but the exposed surface affects aesthetics.
