ASTI Quality

Superior Quality
Our Quality is carried throughout our entire process. Our ISO 9001:2000 Certification demonstrates our commitment to strict quality control policies and procedures. ASTI raw material suppliers comply with the European Union Hazardous Materials Directive. Therefore, our customers can trust that they will receive the premium products they need.

Raw Material & Slitting

As part of our quality control procedure,
all raw material is 100% inspected
during the slitting operation. By slitting
our own material our customers benefit.

• Improved quality
• Greater production flexibility
• Shorter lead-times

Tube Mills

As the old saying goes, if you want something done right, you do it yourself. That is why we designed and built our own equipment to gain the following advantages:

a. Ease of monitoring
b. Ease of adjusting
c. Production of a rounder tube
d. Better seam clean up which makes for better finishing qualities

We follow a scheduled preventative maintenance program on all of our equipment to ensure repeatability and reliability is upheld.

Also, our ISO 9001:2000 program ensures that our operators are well trained and capable of maintaining a high standard of workmanship at all times.

In order to provide a product that has consistent and reliable fabricating properties, all of our tubing is TIG welded. All 304, 304-L, 201 and 316-L strip is domestically produced to our close specifications.


Finishing
We have built our own tube mills, buffers and polishers in-house to provide better controls and to furnish the highest quality and consistent finishes. Our patented process for providing a true mirror finish has placed us as the leader in this field.

In addition to the standard 180, 240, 320, Super buff and Linear Buffed material, we can also try to match a finish to a sample provided by our customer. Please use our online Quotation Request to tell us what you need.

For maximum protection, material is packaged directly off the polishing/buffing equipment.

Packaging
All polished or buffed tubing is covered with vinyl (Linear Buff finish), paper or plastic wrap and heavy duty packaging to protect all finishes we use. We will band, bundle, or box your order for optimal shipping.
