At Paneltech International LLC (PTI), engineering credibility and product verification form the bedrock of our manufacturing operations in Barka, Oman. For global EPC contractors, engineering consultants, and commercial developers, technical certifications are not merely documents—they are verified guarantees of life-safety, structural durability, and energy efficiency.
Our PIR, PU, and Rockwool sandwich panel systems, corrugated profile sheets, and cold-formed Z & C purlins undergo strict continuous testing conforming to recognized ASTM, BS, and EN standards. Every production cycle is governed by documented quality control plans to ensure complete conformance with strict international specifications.
Procurement teams and project consultants require verified submittal packages during the Material Approval Request (MAR) phase. Paneltech provides complete engineering portfolios including:
Documented approvals confirming our production management compliance, safety protocols, and conformity to civil and industrial building standards.
Certified operational compliance covering the design, roll-forming, core blending, and continuous lamination of insulated sandwich panels and profiled sheet systems.
Official registration and quality conformity verification validating production adherence to national building safety protocols, structural integrity, and industrial code compliance.
Accredited verification confirming factory equipment calibration, raw material specification control, fire behavior performance, and finished product dimensional precision.
Paneltech insulated panels and secondary structural systems are manufactured and evaluated according to leading international testing methodologies.

How Paneltech maintains consistent batch uniformity across millions of square meters of insulated panel production.
Steel coils are inspected for paint thickness, zinc coating adhesion, and yield strength. Polyol and isocyanate chemical inputs undergo density and reaction audits before feeding the line.
Automated temperature, roll-forming profile consistency, polyisocyanurate foam density, and continuous curing tunnel heat profiles are digitally monitored in real time.
Representative batch cut-offs are tested for core-to-steel tensile adhesion, dimensional tolerances, flexural strength, and thermal conductivity in our dedicated Barka laboratory.
Panels are packaged with UV-stabilized protective film, high-density edge protectors, and waterproof plastic strapping. Complete Mill Test Certificates are issued per release.
Clear answers for engineers, quantity surveyors, and project managers reviewing compliance credentials.
Yes. Paneltech PIR and Rockwool insulated sandwich panels are engineered and tested in accordance with international fire safety benchmarks (such as ASTM E84, ASTM E119, and EN 13501-1) and hold relevant compliance approvals required by regional Civil Defense authorities and engineering consultants.
Paneltech International LLC operates under strict ISO 9001 certified quality management protocols, ensuring rigorous raw material verification, in-process continuous testing, and final quality control documentation for every production batch.
Yes. For every tender and commercial order, Paneltech provides complete Material Approval Request (MAR) submittal packages containing raw steel coil Mill Test Certificates, insulation core density and adhesive test results, fire rating certificates, and third-party laboratory verification.
PIR (polyisocyanurate) is a fire-retardant thermoset polymer that chars upon exposure to flame without producing flaming droplets, achieving Class A rating under ASTM E84. Rockwool consists of natural volcanic basalt stone fibers, offering complete non-combustibility and tested structural fire ratings up to 2-3 hours under ASTM E119 / BS 476 Part 22.
