How Thick Should TIS-Standard Aluminum Be to Be Considered High Quality?

The standard aluminum thickness for door and window projects in Thailand is 1.2–2.0 mm. TIS 284-2560 specifies the required thickness and weight per meter for extruded aluminum profiles. Technicians who choose aluminum that meets the standard will achieve stronger work that resists warping and clearly lasts longer than non-TIS aluminum.

TIS-Standard Aluminum Thickness: Choose Correctly from the Start with SGQ Khlong Sam

When talking about standard aluminum thickness, many people are familiar with numbers such as 1.2, 1.5, 1.8, and 2.0 mm, but they may not know where these numbers come from or why choosing the wrong thickness can affect the entire project. This article is different from general guides that recommend thickness by application type. Here, we will take a closer look at the TIS standard: what it specifies, how it is measured, and how non-standard aluminum affects real job sites. For more information on choosing the right thickness for each panel type, you can read the article “Recommended Aluminum Thickness for Door and Window Projects.”

What Aluminum Thickness Does the TIS Standard Specify?

TIS 284-2560 specifies that extruded aluminum profiles must have wall thickness and weight per meter that match the specifications submitted for certification. For door and window projects in Thailand, the commonly used thickness range is 1.2–2.0 mm, with each thickness suitable for different loads and panel sizes.

  • 1.2 mm: Light-duty work, such as small windows or interior sliding panels.
  • 1.5 mm: General work most commonly chosen by technicians, such as sliding doors and awning windows.
  • 1.8–2.0 mm: Heavy-duty work that needs to support greater force and weight, such as frameless-style panels, full-glass panels, and exterior doors. Each type of glass has a different weight. Read more in “Processed Glass vs. Standard Glass” to choose the correct frame thickness.

Professional technicians usually choose aluminum thickness based on panel size and installation location, not by price alone.

What Problems Can Non-Standard Aluminum Thickness Cause?

Aluminum with thickness that does not match the specification or does not meet TIS standards often shows clear problems within 1–3 years after installation, such as shaking panels, bent frames, and issues that are difficult and more expensive to repair than choosing the right materials from the start.

  • Too thin: shaking panels, wind noise, and bent frames after long-term use.
  • Too thick: unnecessary budget waste and heavier panels that cause hardware to wear out faster.
  • Non-TIS standard: peeling color, uneven surface, and weight that does not match the specification.

However, aluminum that is thicker than the project requires is not always the best solution, because heavier panels can cause hardware to wear out faster than normal.

Problem Found Cause Impact
Shaking panels and wind noise Too thin and unable to withstand wind pressure The entire panel set may need to be replaced
Bent or deformed frames The thickness cannot support the glass weight The glass may crack if the frame bends too much
Peeling color and uneven surface Does not meet TIS 218 surface coating standards The work may look old within 2–3 years
Hardware wears out quickl The aluminum is thicker than necessary, making the panel too heavy Repair costs for rollers and sliding tracks increase

How Is Each TIS Number Related to Aluminum Thickness?

Each TIS number controls a different aspect of aluminum quality. Understanding what each standard covers helps you choose and inspect materials more accurately.

  • TIS 284-2560: Extruded aluminum → Checks the correct thickness and weight. Aluminum profiles that meet this standard have strength and durability according to specification. Read more in “Strong and Durable Aluminum Profiles.”
  • TIS 218-2520: Anodized aluminum → Controls coating quality.
  • TIS 744-2563: Finished aluminum door and window systems → Tests wind pressure resistance, water resistance, and overall strength.

If an aluminum profile does not have “TIS,” it may mean the thickness does not match the specification or the material quality is not up to standard.

Standard Thickness Suitable for Each Type of Work

Thickness Suitable Work Type Related TIS Standard Precautions
1.2 mm Small windows and interior sliding panels TIS 284-2560 Not suitable for exterior use or large panels
1.5 mm Sliding doors and awning windows TIS 284-2560 ✅ The thickness most commonly chosen by technicians
1.8 mm Exterior doors and swing panels TIS 284-2560, 744-2563 Also check TIS 744
2.0 mm+ Full-glass panels, frameless-style panels, and security doors TIS 284-2560, 744-2563 Requires a specialized installation technician

Standard Aluminum Window Sizes and the Required Thickness

Standard aluminum window openings in Thailand are usually 60×110, 80×110, and 100×110 cm. The opening width and glass weight determine how thick the aluminum frame should be. For projects using European aluminum profile systems, which have different thickness specifications from Thai systems, always check the specification table of that specific system first.

How Thick Should Standard-Sized Sliding Aluminum Windows Be?

For general sliding aluminum windows with openings up to 100 cm wide, aluminum frames with a thickness of 1.2–1.5 mm can be used safely. However, if the aluminum window frame needs to support heavier glass or an opening wider than 120 cm, the thickness should be increased to 1.5–1.8 mm to prevent long-term frame warping.

How Thick Should an Aluminum Window Frame Be to Meet the Standard?

An aluminum window frame that meets TIS 284-2560 must have a profile wall thickness that is not lower than the specification stated for each profile. A basic way to check is to use a vernier caliper to measure the thinnest wall section of the aluminum profile. If the measured value is 0.1 mm or more below the specification, it is considered non-standard.

How to Check Whether the Aluminum You Bought Has the Correct Standard Thickness

Aluminum thickness can be checked both visually and with measuring tools. Professional technicians usually check both ways before accepting materials for the job site.

  1. Check the panel size: Larger panels require greater thickness.
  2. Check the installation location: Interior use can be thinner / exterior use requires thicker aluminum.
  3. Ask for TIS certification: To ensure the aluminum truly meets the standard thickness.
  4. Choose a trusted brand: Such as ORM, Fuji Metal, and Schimmer, which provide clear specifications.

Frequently Asked Questions: Standard Aluminum Thickness

1. What Aluminum Thickness Does the TIS Standard Specify?

TIS 284-2560 does not specify one fixed thickness number. Instead, it requires the thickness and weight per meter to match the specifications submitted by the manufacturer for certification. In practice, the thickness commonly used for door and window projects in Thailand ranges from 1.2–2.0 mm, with 1.5 mm being the most popular choice for general work.

2. How Can You Measure Aluminum Thickness at a Basic Level?

Use a vernier caliper to measure the thinnest wall section of the profile. The measured value should match the specification stated in the TIS document or factory certificate. If the value is more than 0.1 mm below the specification, it is considered non-standard, and that material lot should be rejected.

3. How Are Standard Aluminum Window Sizes Related to Thickness?

The opening size and glass weight determine the required frame thickness. For sliding windows with openings up to 100 cm wide, 1.2–1.5 mm aluminum can be used. However, if the opening is wider than 120 cm or heavier glass is used, the thickness should be increased to 1.5–1.8 mm to prevent frame warping.

4. How Is Non-TIS Aluminum Different from TIS-Certified Aluminum in Practice?

Non-TIS aluminum may have uneven thickness throughout the profile, thin surface coating, color that peels easily, and weight per meter that does not match the specification. This affects both strength and service life. For project work or high-rise buildings, TIS documents are required by construction inspectors every time.

5. Where Can You Buy TIS-Standard Aluminum with Certification Documents?

SGQ Khlong Sam sells TIS-standard aluminum from several brands, including ORM, Fuji Metal, Thai Metal, and SMS Schimmer. The store provides clear specifications and a team ready to advise on choosing the right thickness for each type of work. For inquiries, call 081-885-2629.
