Your Steel Swing Installation Checklist - Step by Step
Two people. A few hours. Our step-by-step process. Steel and wood - no crane needed. You can do this.
Step 1: Measure where the gate will go
Measure twice. Write it down.
- We recommend a minimum of 2" clearance from any object the posts may be up against (e.g. house, shared neighbor fence, etc.)
- Mark the location where the posts will be installed with white paint
- ⚠️ Call 811 to have underground utilities located before you dig
Step 2: Dig the post holes
- Once the area has been cleared and there are no obstructions, dig the post holes
- We recommend a minimum 18" x 18" x 36" hole for each post (depth and size can increase depending on how solid the ground is)
- More concrete and larger hole size required for solo gates
- Use crushed base rock at the bottom of the hole for extra help with drainage and support for posts
Step 3: Find the absolute highest elevation in the gate's path
- Use a tape measure and a level to determine where the highest elevation is in the path of the gate (open, closed, and along the arch of the gate)
- Once the highest point along the path of the gate has been found, set the posts to that height and level across to the next post. Post height from highest elevation point provides a minimum of 2" clearance underneath the gate
- Top of post 61" plus highest elevation point for Arch Top Gates (the posts might be higher than this depending on the elevation point)
- Top of post 73" plus highest elevation point for Flat Top Gates (the posts might be higher than this depending on the elevation point)
Step 4: Screw in hinges once posts have been set
- Setting time is a minimum of 2-4 hrs for fast-drying concrete and 1-3 days for standard concrete
- With provided hinges, screw in the bottom hinge into the gate post (the hinge with only 1 nut)
- For recommended 4" hinge spacing, the center of the adjustable bolts should be 2⅝" from the post
- For the top hinge, remove the second nut
- Slide the hinge bolt through the top hole of the post and then reach inside and tighten the second nut so that you acquire the 2⅝" spacing as specified above
Step 5: Grease the hinges and insert the ball bearing
- We recommend using standard car grease (roughly 2 pumps if using a grease gun, or a generous amount if by hand)
- Using a screwdriver or your pinky, push in the ball bearing into the barrel of the hinge so that it stays lodged at the top (we recommend wearing rubber gloves)
Step 6: Hang and adjust the gate
- We recommend using 2 or more people for hanging the gate
- Carefully lift the gate and position it so that barrels of the gate are directly over the top of the ¾" adjustable bolts you inserted into the posts (Step 4)
- Lower the gate so that the barrels slide over the adjustable hinge bolts (might only slide on slightly at first)
- Once the gate is resting on the adjustable hinge bolts, swing the gate carefully back and forth so that the gate is seated fully (there may be a ⅛" gap between the welded washer on the adjustable hinge bolts and the bottom of the barrel)
- If the gate is not aligned, loosen the top bolt of the hinges and lift the gates in the center so that they match and are level (you can use a 2" wedge underneath the gate)

From Order to Operating: Your Steel Swing Gate Timeline in San Antonio
Most projects take 6–14 weeks. Here's what happens when.
| Phase | Duration | Details |
|---|---|---|
| Permit approval | 1-3 weeks | Building permit required for structures over 6 ft; SAWS utility clearance needed. Plan accordingly. |
| Fabrication | 2-3 weeks | Custom fabrication after design approval |
| Shipping | 3-7 days | LTL freight; lift-gate trucks available for easy curbside unloading; kits can be unloaded piece by piece on the truck for lighter handling |
| Site preparation | 1-2 days | Excavation, concrete footings, utility trenching |
| Installation | 1-2 days | Gate hanging, operator mounting, electrical, commissioning |
Total project timeline: Typically 6–14 weeks from initial consultation to operating gate, depending on permit speed and fabrication complexity.
San Antonio scheduling tip: San Antonio soil is primarily limestone and caliche. Post holes require a rock drill, not just an auger - budget an extra $300-$600 for drilling through limestone.

Specs That Matter: Steel + Swing
Steel At a Glance
| Weight | Heavy (150-400 lbs per panel) |
| Rust | Moderate - needs paint or protective coating |
| Upkeep | Check once a year. Touch up paint every 3-5 years |
| How long it lasts | 30-50 years with good care |
| Best for | Security first, Business driveways, Windy areas, Wide openings |
GateFrames steel gates are engineered for 2-person install - no crane needed.
Swing Gate At a Glance
| Min width | 8 ft (single panel) |
| Max width | 20 ft (two panels) |
| Space needed | Clear space for gate to swing - usually 10-12 ft |
| Best for | Flat driveways, Gentle slopes |
| Opener type | Arm opener or underground opener |
Swing gates are the oldest type. Simple. Reliable. Still the most popular.
When to Choose Steel
✅ Choose when:
- Security is your top priority. Steel is hard to cut.
- You need a wide opening (20+ ft). Steel does not sag.
- It is windy. Steel is heavy. It holds steady.
- You want a modern, clean look with durable paint
❌ Think twice when:
- You live near the ocean and do not want to maintain it
- Your budget is under $3,000 for everything
💡 Pro tip: Steel looks great with stone, stucco, or concrete. Match the gate color to your trim or garage door.
Swing Gate: What to Know
Best for: Flat or gentle slope. Under 16 ft wide. Clear space on one or both sides. Two panels with underground opener = cleanest look. No visible motor.
⚠️ Watch out: Not leaving enough room. A 12-ft gate needs 12 ft of empty space to swing. No plants. No cars. No mailbox. On a slope, the gate can hit the ground on the high side.
💡 Pro tip: Swing inward if you can. Keeps the gate off the street. Hides the opener. Looks cleaner. Exception: steep uphill driveways where inward swing drags on the ground.
Steel vs Other Materials for Swing Gates
How does steel stack up? Here's the side-by-side comparison.
| Factor | Steel | Wrought Iron | Aluminum | Wood |
|---|---|---|---|---|
| Weight | Heavy | Heavy | Light | Medium |
| Lifespan | 30-50 years with good care | 50-100+ years with good care | 30-40 years | 15-25 years. Depends on wood type and weather |
| Maintenance | Check once a year. Touch up paint every 3-5 years | Check twice a year. Repaint every 2-3 years | Clean once a year. Little else | Seal or stain every 1-2 years. Check hinges often |
| Mid-range cost | $4,500-$8,000 | $5,500-$10,000 | $3,500-$6,500 | $3,000-$5,500 |
Local Considerations for San Antonio
Every market is different. What works in one city may cost more or require different permits in another. Here's the San Antonio breakdown.
State: TX Climate zone: Dry Heat Permits: Building permit required for structures over 6 ft; SAWS utility clearance needed
San Antonio Properties & Styles
Typical lots: Ranch-style lots in outer suburbs, traditional lots in Alamo Heights and Terrell Hills, acreage properties north of 1604 Popular gate styles: Wrought iron with Spanish colonial details, rustic wood and iron combinations, Hill Country stone pillars with metal gates
HOA & Architectural Review
Heads up: HOAs in new developments (Stone Oak, Helotes) are moderately strict. Older neighborhoods like Alamo Heights have architectural review but are more flexible on traditional designs.
Climate Impact on Gate Selection
UV exposure degrades powder coatings and dries out wood. For gates in San Antonio, choose UV-stabilized powder coat colors; apply UV-protectant sealant to wood gates annually.
Recommended inspection frequency: Inspect coatings quarterly, lubricate moving parts every 3 months
Steel in San Antonio's Climate
Steel absorbs and radiates heat aggressively. In desert climates, dark-colored steel gates can exceed 150°F surface temperature - painful to touch and hard on operator seals. Choose lighter powder coat colors and specify heat-rated operator gaskets.
San Antonio Cost Factors
Labor and material costs in San Antonio run approximately 8% below the national average. Use this when comparing quotes - a $10,000 gate in Texas might be $12,000–$14,000 in San Antonio.
Local Installer Tip
San Antonio soil is primarily limestone and caliche. Post holes require a rock drill, not just an auger - budget an extra $300-$600 for drilling through limestone.

What Installers Wish You Knew (Before You Sign)
Methodology note: These tips come from common real-world install patterns. Always double-check local code, utility clearances, and your driveway layout before you start.
💡 Steel Swing
Ask for a drip edge on the bottom. It lets water run off. Without it, water pools and rust starts from the inside. A $50 add-on saves thousands later.
