Office staples should be the most reliable tools on your desk, not the biggest headache. We break down what separates a true heavy-duty stapler from a disposable plastic desk toy, featuring Sinsun's jam-free anti-corrosion lineup.
Sinsun Office Staples are standardized metal paper fasteners for universal binding of office documents, sorting of files and organizing of stationery. These staples are made to mainstream and heavy duty specs and fit all manual and electric office staple guns on the market. Office staples have fine polished edges, moderate hardness and flat clinch performance, which prevents paper surfaces from being damaged or document edges from being torn. Industrial staples have thick edges and tend to be extremely hard.
Sinsun is a professional manufacturer of stationary fasteners, using fine low-carbon steel raw material and full-automatic precision stamping technology to produce office staples. Each staple is edge deburred and surface galvanized to eliminate sharp burrs and rust spots.
One of Sinsun's key differentiations is its ability to optimize multi-scenes for optimal batch quality. Most office staples on the market have uneven hardness and poor rust resistance. Our products have long-term oxidation resistance and a durable clamping force. We also provide bulk wholesale customization and mixed specification packaging, fully meeting diverse B2B and B2C procurement needs for office stationery.

Our teachers used to break three staplers a year. "It's still going strong.”“Kids are not soft." The metal construction on this Sinsun office stapler withstood four desk knock-offs last semester. And reloading is easy, even with arthritis."

High-Frequency FAQ for Sinsun 80 Series Staples
Q1
How many sheets does a regular heavy duty office stapler staple?
Standard heavy duty units bind 60 to 250 sheets depending on the leverage mechanism. Sinsun’s HD series staples up to 110 sheets with standard 24/6 staples on 80gsm paper.
Q2
I have a Sinsun stapler that is jammed! How do I uninstall it?
The jam-release button is located underneath the staple channel. Use a remover to remove the bent staple and press back into the channel until it clicks. Our anti-jam geometry effectively eliminates deep clogs.
Q3
Will Sinsun standard staples work on all electric stapler models?
Yes, our universal 24/6 and 26/6 full strips fit both our manual electric desktops and mechanical lever units. For high volume (5,000+ daily bins), we recommend our proprietary S-Cartridge for continuous auto-feeding.
Q4
Which throat depth do I need to saddle-stitch booklets?
More than 8" With a long reach of 12 inches, the Sinsun series of long arms allow you to place a staple exactly at the spine center of an open A3 booklet.
Q5
How deep does the throat have to be for full magazine binding?
Our manual heavy duty line has been fatigue tested on the steel drive channel to over 100,000 jam free cycles before part replacement. The body is rated for 5+ years of high volume office use.
Q6
What causes staples to jam?
Usually a worn anvil plate or cheap staples. Sinsun Hammers the legs perfectly inward (flat clinch) on a hardened steel anvil. We also recommend zinc-plated staples for consistent leg penetration and avoid buckles.
Q7
Will a heavy duty stapler work on fabric or light corrugated?
A: Metal roof fasteners always include a sealing washer and a self-drilling point – ordinary screws have neither.
Q8
Q: Can sheet metal roofing screws work on corrugated panels?
A: Only if those sheet metal roofing screws have bonded washers – bare ones won’t seal the overlaps.
Q9
Q: Do I need the exact brand for replacement screws for metal roof?
Yes. Holds thin corrugated fiber, denim and canvas for display or light packaging. Our plier-style heavy-duty units with B8 PowerCrown staples securely bind items as the wide crown distributes and holds pressure evenly.
10
Does Sinsun have a green/ECO-friendly stapler that is certified?
Definitely. Our stapleless line contains no metal parts at all. The plastic housing of our new series is made from 97% post-consumer recycled plastic, fully compliant with international ISO 14001 green manufacturing standards.
