Why the Galaxy S8 Plus Black Metal Gorilla Case Is Essential for Outdoor Enthusiasts and Heavy-Duty Workers
Some phones get babied. Yours gets bolted into armor. This black metal Gorilla Case wraps your Samsung Galaxy S8 Plus (2017, 6.2-inch Infinity Display) in an aerospace-grade aluminum and super zinc alloy exoskeleton, lined with a shock-absorbing TPU sleeve and locked together with six front screws — real hardware, driven home with the included screwdriver, so the case cannot shed panels when it hits the ground. A silica gel gasket seals the seams against rain, beach sand, and shop dust, and the silicone inner layer rises above the big curved screen so the glass never touches down first. It is heavy, it is bulky, and that is the point. Built for soldiers, riders, truck drivers, outdoor enthusiasts, and anyone who wants their S8 Plus genuinely well protected, this is the best Galaxy S8 Plus heavy duty metal case for people who use their phone like a tool. Welcome to the Gorilla Family.
Key Features
- Tactical black finish: matte anodized metal that hides scuffs and looks equally right on a tailgate or a conference table.
- Premium materials: aerospace-grade aluminum frame, super zinc alloy screw posts and corners, quality TPU inner sleeve, and toughened glass elements.
- Case type: full-body bolt-together metal armor — six front screws clamp the frame shut so impacts cannot pop it open.
- Tool kit included: a precision screwdriver and spare screws come in the box — install, remove, and reinstall for years.
- Water, sand, and dust resistance: the silica gel seal and gasket laugh off rainy days and seaside trips — though this is weather armor, not a dive housing, so no swimming or soaking.
- Screen protection: the raised silicone inner layer sits proud of the 6.2-inch curved display — pair it with a case-friendly screen protector for full coverage (one is not included with this model).
- Camera protection: a precisely reserved cutout recesses the 12 MP camera away from tables, truck beds, and concrete.
- 10 ft / 3 m drop protection: the aluminum frame distributes the impact while the TPU sleeve and zinc alloy corners soak it up.
- Charging compatibility: the USB-C port stays fully accessible for fast charging; honest note — Qi wireless charging does NOT work through a solid metal body, so plan on the cable.
- Metal headphone buckle: a reinforced opening guards the 3.5 mm jack and accepts standard plugs without an adapter.
- Compatibility: machined for the Samsung Galaxy S8 Plus (2017, 6.2-inch) ONLY. It does NOT fit the Galaxy S8, S8 Active, S9, S9 Plus, or Note 8.
Materials Explained — What Aluminum and TPU Actually Feel Like
The outer frame is aerospace-grade aluminum — the same alloy family that builds aircraft fuselages and downhill mountain bike frames. It feels cold and rigid in hand, knocks like metal because it is metal, and refuses to flex on impact, spreading a corner hit across the entire shell instead of letting it concentrate on one point.
The screw posts and corner hardware are super zinc alloy — the dense metal used in carabiners and commercial door fittings — so the six front screws thread in firm and true, install after install, without stripping.
Inside, a quality TPU sleeve cradles the phone — the rubbery polymer from running shoe soles and hockey puck rims. Hard shell spreads the blow, soft sleeve absorbs it. And because the S8 Plus's edge-to-edge curved glass makes a front panel impractical, the silicone inner lip is raised above the display so the case, not the screen, takes the landing.
All in, the case weighs about 11.3 oz (320 g) and adds roughly 3.5 mm of thickness. Heavy and bulky but tough — it is a deliberate trade, and it is why a 10 ft / 3 m drop onto concrete reads as a scuff, not a catastrophe.

Real-World Use Cases
- The Motorcycle Rider: bar-mounts the S8 Plus for navigation knowing vibration, gravel spray, and the odd tip-over are all within spec.
- The Site Supervisor: drops the phone off a mezzanine onto a concrete slab and finishes the walkthrough — the frame takes the dent, the phone takes the call.
- The Long-Haul Driver: the phone lives on the dash, falls into the footwell weekly, and hits fuel-stop tarmac monthly. Still going.
- The Camping Family: rain on the tent, sand in the bag, kids around the fire pit — the gasket and the armor handle all three.
- The Gift-Giver: a screwdriver-assembled metal case for the outdoorsman who refuses to upgrade his S8 Plus — half tool, half toy, fully appreciated.
Feature-to-Benefit Mapping
| Feature | Benefit |
|---|---|
| Aluminum and zinc alloy exoskeleton | Survives 10 ft / 3 m drops onto concrete by spreading impact across the whole frame |
| Six-screw front fixation | The armor physically cannot pop open on impact — it stays shut until you unscrew it |
| Silica gel seal and gasket | Rain, beach sand, and shop dust stay outside where they belong |
| Raised silicone inner lip | The 6.2-inch curved display never touches the surface it lands on |
| Included screwdriver and spare screws | Years of installs and removals with zero trips to the hardware store |
Step-by-Step Installation Guide
- Clean your Galaxy S8 Plus with a microfiber cloth — and if you use a screen protector, apply a case-friendly one now, before assembly.
- Seat the phone into the TPU inner sleeve, aligning the camera, rear fingerprint sensor, and port cutouts.
- Place the aluminum front frame over the phone and hand-start all six screws into their zinc alloy posts.
- Tighten gradually in a criss-cross pattern with the included screwdriver — snug, not crushing, so the gasket compresses evenly.
- Verify the buttons, USB-C port, headphone jack, and fingerprint sensor, then stash the spare screws somewhere memorable.
Troubleshooting and Tips
- Buttons feel stiff after assembly? Loosen each screw a quarter turn and re-tighten evenly — one over-torqued corner pinches the button rail.
- Wireless charger not detecting the phone? Expected — Qi cannot pass through solid aluminum. Use the USB-C port for fast charging.
- Gasket bulging at one edge? Disassemble, re-seat the seal flat in its channel, and screw back together — an even gasket is what keeps grit out.
- Dropped a screw in the grass? That is what the spares are for; if you exhaust them, contact our team and we will sort you out.
- Cleaning advice? Wipe the metal with a dry or lightly damp microfiber cloth — avoid alcohol wipes, which dull the anodized black finish over time.
FAQs
Which phones does this case fit?
It fits the Samsung Galaxy S8 Plus (2017, 6.2-inch Infinity Display) only. It does NOT fit the Galaxy S8, S8 Active, S9, S9 Plus, or Note 8. We make the same armor sized for the standard S8.
What comes in the box?
The metal case (aluminum front frame plus TPU-lined back), a precision screwdriver, and spare screws. A screen protector is NOT included with this model — we recommend adding a case-friendly one.
Does wireless charging work through the case?
No — straight answer: Qi charging cannot pass through a full metal body. The USB-C port remains fully accessible and supports Samsung fast charging.
What is the drop protection rating?
Roughly 10 ft / 3 m onto concrete — the aluminum frame spreads the impact, the zinc alloy corners and TPU sleeve absorb it.
Is this case waterproof?
It is water resistant, not waterproof. The silica gel seal and gasket handle rainy days and seaside trips with ease, and general sand and dust cannot get in — but it does not support swimming, soaking, or depth diving. For submersion, see our dedicated waterproof S8 Plus case.
Why is there no glass over the screen?
The S8 Plus's edge-to-edge curved display makes a rigid front panel impractical — it is very difficult to produce front glass for this curve. Instead the silicone inner layer rises above the screen so drops land on the case. Add a case-friendly screen protector for scratch coverage.
Does the rear fingerprint sensor still work?
Yes — a reserved cutout leaves the sensor fully exposed and easy to find by feel.
Are the buttons and ports accessible?
Yes. Power, volume, and Bixby respond through metal-backed button pads, and the USB-C port and 3.5 mm headphone jack have reinforced openings — the metal headphone buckle takes standard plugs without an adapter.
How heavy is it?
About 11.3 oz (320 g). This case is deliberately heavy, bulky, and tough — if you want featherweight, look elsewhere; if you want the phone to outlive the truck, this is it.
Will the black finish wear off?
The anodized coating is bonded into the aluminum, not painted on, so it resists chipping and fading. Hard encounters with steel or concrete may leave marks — they wear like scars on a tool, not damage.
Is it professional enough for the office?
Yes — matte black metal reads rugged-professional, more tactical watch than toy. It starts conversations for the right reasons.
Can I attach a lanyard?
There is no dedicated lanyard hole — the six-screw clamp is the retention system. Pair with a belt holster if you want body carry.
Is this a good gift?
One of our favorites to give — the screwdriver assembly makes unboxing an event, and the armor keeps a beloved S8 Plus alive for years. Free 30-day returns make it risk-free.
What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy S8 Plus cases. If the case doesn't fit your Galaxy S8 Plus or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.
How long does installation take?
About ten minutes the first time, five once you have done it — six screws, one included screwdriver, no surprises.

What Gorilla Family Customers Are Saying
★★★★★
Came off the bike at low speed — phone fine
Low-sided on gravel with the phone in my jacket. The case has a gouge across one corner and the phone does not have a mark. The screws never loosened despite months of handlebar vibration. Buying a second one for my old S8.
— Diego R., Albuquerque, NM
★★★★★
The assembly is half the fun
Felt like building a tiny tank around my phone. Everything lines up perfectly, the screwdriver included is decent quality, and the spare screws live in my desk drawer. Months of warehouse work and zero damage.
— Pete S., Birmingham, UK
★★★★★
Survives my fishing trips
Rain, sand, tackle boxes, and one bounce off the boat ramp — the S8 Plus inside is pristine. The gasket really does keep grit out; I blow the seam clean after beach days and that is all the maintenance it needs.
— Wade C., Tampa, FL
★★★★★
Husband-proof at last
My husband has destroyed three phones in two years. This case has outlasted them all — ladder drops, a lawnmower incident, a winter in his truck. He loves showing people the screws. Best gift I have bought him.
— Andrea F., Edmonton, AB, Canada
★★★★½
Tank protection, plan for cable charging
Nothing has scratched the phone since day one and concrete drops are non-events. Two honest costs: it is genuinely heavy in a shirt pocket, and my wireless charging pad is now decorative. Cable charges fast, so I adapted — worth it.
— Lewis T., Denver, CO
