01 / MINING
Mining-safety mark documents
The historic catalogue reproduces mining-product safety documents. Certificate holder, model scope, issuing authority, expiry and current validity must be checked before use in a tender.
DOCUMENTATION & COMPLIANCE
Quality & Documentary History
Technical documentation matters more than general claims. Our historical catalogue records certificates, inspection material and enterprise recognition.
What the original catalogue documents
02 / TESTING
Product inspection records
The booklet includes product-inspection materials and strength tables for reinforcement and anchor systems. Historical figures are not automatically current guaranteed values.
03 / TECHNICAL HISTORY
Patents & recognition
The catalogue reproduces patent-related records and enterprise/technology awards. These are part of AOWO's documented history and are not treated as proof of active patent rights.
04 / CURRENT ORDERS
Project-specific verification
For quotations, obtain the current supplier's signed datasheet, test report, relevant standard, model number and approval documents for the actual product and grade.
Historical documents are not current certificates. Scanned originals are deliberately not edited or reissued. Once the current authorized certificates are available, this page can show original-document images, certificate numbers and expiry dates.
