Our Quality Assurance System

A Documented Path From Material to Delivery

Our control system focuses on consistency, traceability, and application-oriented quality so customers can evaluate each batch with confidence.

  1. 01

    Raw Material Inspection

    Incoming materials are checked against defined requirements before they enter the production process.

  2. 02

    In-Process Control

    Key production parameters are monitored to maintain process stability and reduce variation between batches.

  3. 03

    Finished-Product Testing

    Finished products are tested against relevant specifications before release for shipment.

  4. 04

    Release & Traceability

    Batch records, retained samples, and COA documentation support transparent product release and follow-up.

Eight Quality Pillars

More Than a Final Inspection

Reliable quality comes from disciplined control throughout the manufacturing cycle, not from a single final test.

Our quality objective

Deliver products that are stable, traceable, and suitable for customers' actual application requirements.

1. Raw Material Inspection

Supplied materials are identified, reviewed, and inspected before use to help protect downstream product consistency.

2. In-Process Control

Defined operating conditions and inspection points help ensure that each production step remains under control.

3. Finished-Product Testing

Each finished batch is evaluated according to applicable technical requirements before approval for release.

4. Application Testing

Application-oriented testing supports product selection for mortar, tile adhesive, wall putty, gypsum, and other uses.

5. Retained Samples

Samples are retained by batch to support future verification, investigation, and comparison when required.

6. Batch Records

Production and inspection records create a clear, reviewable history for each manufacturing batch.

7. Nonconforming Product Handling

Products that do not meet requirements are identified, segregated, reviewed, and handled through controlled procedures.

8. COA Traceability

The Certificate of Analysis links released product data to its identified batch for transparent customer documentation.

Certificate of Analysis

Clear Documentation for Every Released Batch

A Certificate of Analysis provides the tested batch information customers need to confirm product identity and review relevant quality data before use.

  • Batch identification: Connects documentation to the corresponding production batch.
  • Tested quality data: Records the relevant results for the released product.
  • Traceable records: Supports quality review, customer communication, and follow-up when needed.
