購入ガイド: A3 Magnetic Frames
📋 目次
1What size A3 magnetic frame do I need for standard documents?
Look for a frame with an internal size of at least 300 x 420mm to fit standard A3 paper or posters. Some models offer a 5–10mm border for added stability, which is ideal for thicker or uneven materials like printed photos or laminated charts.
2How strong should the magnets be for secure display?
Magnetic frames for A3 typically use neodymium or ferrite magnets. For lightweight posters or paper, magnets with a holding force of 1–2kg per corner are sufficient. For heavier items like thick folders or 3D objects, look for frames with 3–5kg per magnet to prevent slippage.
3Are A3 magnetic frames suitable for frequent updates or changes?
Yes, but choose a frame with a smooth, non-abrasive inner surface to avoid tearing paper. Frames with a soft felt or foam backing are best for daily use, while those with rigid plastic or glass inserts are better for permanent or semi-permanent displays.
4What materials are best for durability and visibility?
Acrylic or tempered glass panels offer the clearest view and are scratch-resistant, making them ideal for professional or high-traffic settings. Plastic or polycarbonate panels are lighter and more affordable but may yellow or fog over time if exposed to heat or moisture.
5Can I use an A3 magnetic frame on a whiteboard or metal surface?
Yes, but ensure the frame has strong, flat magnets that won’t warp or leave residue. For whiteboards, frames with a matte finish or felt backing prevent scratches. For metal walls, check that the magnets are spaced to avoid interference and allow for even mounting.
