Aluminium Ruler 30 cm Grand — straight measuring ruler 30 cm, metal scale

The Grand Aluminium Ruler 30 cm is a straight measuring ruler designed for precise linear measurements in drawing, drafting, schoolwork and workshop tasks. Constructed from lightweight corrosion-resistant aluminium, it features clear metric graduations engraved along its length for accurate readings up to 30 centimetres. The slim profile and straight edges make it suitable as a cutting guide and for producing consistent, straight lines on paper, card and thin materials.

Advantages

The aluminium construction provides a balance of lightness and rigidity, resisting bending during routine use while remaining easy to handle. Corrosion-resistant surface treatment ensures durable appearance and long-term legibility of the scale. Engraved metric markings reduce wear compared with printed scales and deliver reliable accuracy for repeated measurements. The straight, machined edge offers a stable guide for pencils, pens and utility knives when controlled cutting is required.

Suitable for

• Technical drawing and drafting
• School projects and student use
• Hobby craft, model making and paper cutting
• Workshop measurement and marking of small components

Key specifications

• Length: 30 cm
• Material: aluminium with corrosion-resistant finish
• Scale: metric graduations engraved to 30 cm
• Edge: straight, machined for guiding pencils and cutting tools
• Profile: slim and lightweight for easy handling

How to use

Place the ruler with its straight edge aligned to the points to be measured or marked. For drawing, hold the ruler firmly with one hand to prevent slipping and run a pencil or pen along the machined edge to obtain a straight line. When using as a cutting guide, position the ruler on the material and apply steady, even pressure with a utility knife along the ruler edge; use light, multiple passes rather than excessive force for a cleaner cut. Read measurements from the engraved metric graduations, starting at the zero mark.

Usage recommendations

Store the aluminium ruler flat or hung to avoid distortion. Clean with a soft cloth to remove debris and avoid abrasive cleaners that could damage engraved markings. For precise cutting tasks, use a cutting mat beneath the workpiece and replace the cutting blade regularly to reduce lateral force on the ruler edge.
