Ruler Tetis 30 cm aluminium green — 30 cm metal measuring ruler

Aluminium 30 cm Tetis ruler in green provides a lightweight, straight edge for precise metric measurements, marking and cutting guidance. Constructed from corrosion‑resistant aluminium with clear metric graduations along its length, the ruler is intended for tasks in drawing, drafting and general school or workshop use. The slim profile and firm straight edge support accurate lines and measurements while remaining easy to carry and store.

Advantages

The ruler combines rigidity and light weight thanks to its aluminium construction, ensuring a stable straight edge without excess bulk. Clear, evenly spaced metric graduations permit accurate reading and repeatable measurements. The green finish improves visibility on common work surfaces and offers basic protection against wear and corrosion. Its compact 30 cm length balances reach and portability for everyday tasks.

Suitable for

• Technical drawing and architectural sketching
• School geometry, classroom exercises and student use
• Hobby and craft projects requiring straight cuts or markings
• Workshop layout, marking and guide for cutting tools

Key specifications

• Length: 30 cm
• Material: aluminium (corrosion‑resistant finish)
• Graduations: metric scale with clear millimetre and centimetre markings
• Finish: green coating for improved visibility
• Profile: slim, rigid straight edge suitable for guiding pencils and blades

How to use

Place the ruler with its straight edge along the line or points to be measured or marked. Align the zero mark with the starting point, then read the required millimetre or centimetre graduation and mark through the appropriate notch or edge with a pencil or scribing tool. When using as a cutting guide, hold the ruler firmly in place with one hand and run the blade along the outer edge with controlled pressure to ensure a straight cut. Clean any debris from the edge before precision work to maintain accuracy.

Usage recommendations

For prolonged accuracy, store the ruler flat to avoid bending and avoid heavy impact on the edges. When cutting, use a sharp blade and moderate pressure to reduce edge wear; occasional cleaning with a soft cloth will help maintain clear graduations and the green finish.
