Gobricks Parts Explained: Why Chinese Brick Fans Love Them
In the Chinese brick scene, the name Gobricks — usually shortened to Gaozhuan, literally "high-grade brick" — is treated as a quality guarantee. MOC builders check for it first when restocking parts, and brands check for it first when picking a manufacturing partner. But what actually makes these parts good, and how far ahead of ordinary domestic parts are they? Here is the full breakdown: molds, material, how to identify genuine parts, and a real-world comparison with LEGO.
Who Is Gobricks? From Parts OEM to Quality Benchmark
Gobricks is not a brick brand. It is a dedicated brick part manufacturer, founded in 2014 and headquartered in Guangdong, operating as an OEM/ODM factory focused on part development, mold making and production. In practice, parts inside sets from several domestic brands — Pinqi and Double Eagle among them — are actually produced by Gobricks.
Two things built the reputation:
- High mold precision: tolerances controlled at the international top level, giving consistent clutch and hand feel
- Good material and process: imported ABS with mature injection molding, delivering strong color, strength and wear resistance
In the BrickPlan community, MOCs tagged as using Gobricks parts generally draw more attention — builders assume a smoother build and a more solid finished model.
Core Advantages of Gobricks Parts
1. Mold Precision: The Ceiling for Domestic Bricks
Mold precision is the single biggest advantage. Brick tolerance is measured in "si" (0.01 mm), and Gobricks holds its mold tolerance within ±0.02 mm. That is close to LEGO's ±0.01 mm standard and well ahead of the ±0.05–0.1 mm typical of most domestic brands.
Once precision is there, you notice three things:
- Consistent clutch: the 1st brick and the 1000th brick feel exactly the same
- Solid structures: high-precision parts build frames that hold and resist loosening
- Excellent compatibility: mixes with LEGO and other brands without any trouble
2. Material: The Feel of Imported ABS
Gobricks parts use imported ABS from BASF in Germany. The material's characteristics:
- Vivid color: high saturation that resists fading during long-term display
- High strength: excellent impact and bending resistance, unlikely to crack
- Smooth surface: no burrs or flash, fine hand feel
Ordinary domestic parts more often use domestic ABS or recycled plastic, and the gap in color, strength and surface finish is obvious. That is why many builders opening a bag of Gobricks parts react with "this feels genuinely good".
3. A Wide Part Range
Gobricks currently runs more than 3,000 part molds, covering nearly every category from basic bricks to specialty elements. That means:
- One-stop sourcing for MOC builders: most parts on a parts list can be found in the Gobricks catalog
- Complete supply for brands: no need to split orders across multiple suppliers for different part types
Where Gobricks Parts Get Used
Scenario 1: The Default Choice for MOC Building
When MOC builders restock, Gobricks parts are basically the default option. Whether you are building a street scene, a technic mechanism or a military model, the precision and consistency of Gobricks parts keep the structure stable and the finished model presentable.
If you find a MOC plan you like on BrickPlan, it is worth building it with Gobricks parts for the best building experience.
Scenario 2: Filling Out a Parts Wall
Many builders keep their own "parts wall" for everyday MOC work. When restocking that wall, Gobricks parts are one of the best value options. Compared with LEGO parts, which carry a high unit price, Gobricks parts stay close in quality while costing only 1/5 to 1/3 of the LEGO price — ideal for large MOCs.
Scenario 3: Brand OEM Work
As mentioned above, several domestic brands use Gobricks parts in their premium product lines. If you see a set labelled as using Gobricks parts, you can generally assume the part quality is assured.
How to Identify Genuine Gobricks Parts
Some sellers use "Gobricks quality" as a selling point while shipping something else entirely. So how do you tell real Gobricks parts from fakes?
Method 1: Check the Packaging
Genuine Gobricks bags normally carry the Gobricks logo and an anti-counterfeit mark. The logo is a stylized "GZ" combination, clearly printed in vivid color.
Method 2: Check the Injection Point
Gobricks parts have their injection point (gate) finished very cleanly, with almost no visible trace. Counterfeit parts usually have a rough gate with an obvious bump or sink mark.
Method 3: Feel the Clutch
This is the most direct test. Gobricks clutch feels even, smooth and slightly springy — never sloppy, and never so tight that you have to force a part down. If clutch varies across a batch of parts, it is probably counterfeit.
Method 4: Buy Through Official Channels
The safest route is buying from an officially authorized Gobricks dealer or platform. Gobricks has several authorized dealers in China, and buying through them guarantees genuine parts.
Gobricks vs Other Brands
Gobricks vs LEGO Parts
| Comparison | Gobricks parts | LEGO parts |
|---|---|---|
| Mold precision | ★★★★★ | ★★★★★ |
| Material quality | ★★★★★ | ★★★★★ |
| Part variety | 3000+ | 10000+ |
| Price | Low | High |
| Clutch feel | Tighter but even | Medium and smooth |
Verdict: Gobricks parts are already very close to LEGO in precision and material. The clutch feel differs slightly — Gobricks runs a bit tighter — but given the price advantage, the value is extremely high.
Gobricks vs Ordinary Domestic Parts
| Comparison | Gobricks parts | Ordinary domestic parts |
|---|---|---|
| Mold precision | ★★★★★ | ★★★ |
| Material quality | ★★★★★ | ★★★ |
| Color consistency | ★★★★★ | ★★★ |
| Price | Medium | Low |
Verdict: Gobricks parts beat ordinary domestic parts clearly on every measure. The price is slightly higher, but the quality gain far outruns the price gap.
Buying Advice for Gobricks Parts
If you plan to buy Gobricks parts, a few practical tips:
- Buy in bulk for better pricing: loose-part prices drop as quantity rises, so buying 50–100 of the same spec at once lowers the unit cost
- Stock common sizes first: 2x4 bricks, 2x2 bricks, 1x4 plates and 1x2 plates are used most often and are worth stocking up on
- Watch batch consistency: color consistency is good, but slight shade differences can still appear between batches, so buy everything for a large MOC in a single order
- Buy against a MOC parts list: once you have picked a MOC plan on BrickPlan, export the parts list and purchase exactly what it calls for to avoid waste
Final Verdict: Is It Worth Buying?
Yes. Put mold precision, material and value side by side, and Gobricks parts have essentially no rival among domestic manufacturers. Builders who care about build quality tend to try them once and then not want to go back to no-name parts.
Build the same plan with Gobricks parts and the structural stability and finished look really do move up a level. When you are done, come share the build in the BrickPlan community, or browse other builders' Gobricks MOCs and compare notes on where the tricky steps are.
