FIM Flexy Aluminum 8' x 16' Rectangular Offset Umbrella

Selecting your Umbrella Fabric
Umbrella fabrics offered by the top-line manufacturers we feature are known for their quality features and durability. Fabrics are available in different grades and the price of the fabric is determined by that grade. In general, fabrics are graded based on the cost of producing the fabrics. Manufacturing processes such as weaving and the variety of yarn used are factors which comprise the wholesale cost of the fabric. Each manufacturer determines its own grading standards and the grades will vary from manufacturer to manufacturer.

Choosing Umbrella Size
When determining the size of the shade, it is important to know the size of the area or table you want to shade. A free-standing umbrella should be approximately 5 feet larger than the largest side of the area to be shaded. These are the guidelines for shading your table area:

Umbrella Shade (In Feet)	Table Size (In Inches)	# of Chairs
6' Umbrella Shade	30" cafe or bistro	2
7' Umbrella Shade	36" cafe or bistro	2 - 4
9' Umbrella Shade	48" round or square	4 - 6
11' Umbrella Shade	60" Round or Square and 72" Oval and Rectangular	6 - 8

Umbrella Base Sizing
Generally to determine the weight of an umbrella base, a shade diameter of 7.5’ and under should have a base weight of 25-50 lbs. and for shade diameters more than 8’, a base weight of 50-75 lbs. is recommended. For quick reference, here is a basic umbrella base sizing guide:

Umbrella Shade Size (ft)	Umbrella Positioning	Base Weight Options (lbs)
4.5	Thru Table	30
4.5	Free Standing	40
6	Thru Table	30
6	Free Standing	50
7.5	Thru Table	30
7.5	Free Standing	50
8 or 8 x 10	Thru Table	50
8 or 8 x 10	Free Standing	75
9	Thru Table	50

Patio Umbrella Frames
The typical patio umbrella frame is manufacturer from wood, fiberglass or metals such as aluminum or steel. Wood frames are frequently seen on market umbrellas and offer a natural look to your traditional outdoor setting. Fiberglass and metal frames are usually available with more features than wood and their versatility makes them ideal to coordinate with a variety of outdoor décor styles. If your umbrella will experience heavy use in a high-traffic area such as commercial patio umbrellas, then we strongly suggest that you select an umbrella with the fewest moving parts. Choose an umbrella with a single pole instead of two pole sections. A manual or pulley-lift system will hold up best with constant use and also look for umbrellas with strong couplings used with wood, aluminum or fiberglass umbrella frames.

Wood patio umbrellas

• Poles and frames are made from teak, ash or other hardwoods which are naturally resistant to moisture and insects
• Pole diameters measure 1.375” to 2” in diameter
• Center poles come in one or two pieces
• Manual or pulley with pin lift systems are typical
• Not usually available with tilt option
• Sturdy rib construction but wood ribs aren’t flexible in windy conditions
• Replaceable ribs if broken

Fiberglass patio umbrellas

• Sturdy yet lightweight frames, stronger than aluminum or wood
• Limited finishes compared with aluminum and wood
• Available in solid, one-piece poles or two piece pole models
• Fiberglass ribs are the best option for gusty wind conditions
• Longevity: fiberglass ribs last 4 to 5 times longer than wood or aluminum

Aluminum patio umbrellas

• Available in either one or two piece poles
• Most options for opening and closing: crank, manual lift, pulley, quick lift or remote control
• Options for tilting: push-button, non-tilting, automatic tilting and full rotation (offset umbrellas)
• Widest selection of finishes for frames and poles
• Pole finishes can be powder-coated, anodized or laminated for weather-resistance
• Commercial and heavy-use residential locations should stay away from crank and tilting functions

Patio Umbrella Frame Components
A patio umbrella is manufactured with a frame which comprises its structure. The frame is made up of the pole, the ribs and the finial. It also has several mechanisms which allow it to operate smoothly. These include the lift mechanism, the tilt mechanism, the hubs, and a rotating mechanism in the case of offset umbrellas. To understand how the frame and mechanisms work together, we’ve included some basic information about each of these system components:

Crank
A crank is a handle which, when turned in a clockwise and counter-clockwise motion, opens and closes a patio umbrella. On some umbrellas, the crank also allows the umbrella to tilt to varying degrees to provide directional shade. We do not recommend cranks for umbrellas in commercial use.

Pulley and Push Up
Primarily found on wood umbrellas, the pulley and push up are manual methods of opening a patio umbrella. The pulley method uses a rope to assist in raising the umbrella hub with a system of pulleys. The push up method operates similar to a personal umbrella; you simply grasp the hub of the umbrella and manually guide it up the pole to the desired height. Both of these methods utilize a pin which is inserted through predrilled holes in the umbrella pole just under the hub which keeps the umbrella open. The push up umbrella is our only recommendation for commercial umbrella applications. Pulley and crank umbrellas pose a constant safety hazard to patrons and damage to the umbrella itself.

Hub
There are two hubs in most patio umbrellas. The first moves up and down the umbrella pole and is called the runner hub. The support ribs of the umbrella are fastened to the runner hub and facilitate opening and closing the umbrella. There is a top hub to which an umbrella’s main ribs are attached. This top hub does not move while the main ribs rise and fall as the umbrella is opened and closed.

Finial
A patio umbrella finial performs two functions. It helps anchor the umbrella canopy to the frame of the umbrella. Finials are also a design element which completes the finished look for the top of the umbrella.

Pole
You will find umbrella poles in wood, aluminum, fiberglass, steel, plastic or made of composite materials such as resins. Umbrella poles can be solid or made up of two pieces. In a two piece pole, the pieces are connected together to form the entire pole and this type of umbrella is the easiest to ship and to store. Single piece poles are stronger and more suited to commercial uses such as restaurants, hotels, and condo pool areas because they stand up to strong winds and wind gusts better.

Ribs
There are two kinds of ribs on patio umbrellas. The main ribs outspread from the top hub to the edges of the umbrella canopy. Main rubs are located under the canopy fabric and support the fabric panels. The support ribs are connected to both the runner hub and the main ribs and facilitate the opening and closing motion of the umbrella. The more ribs an umbrella has, the stronger and more stable the umbrella is. The strongest ribs are made from fiberglass which usually last four to five times longer than ribs made from wood or aluminum. Fiberglass ribs are the most wind resistant and most able to withstand strong wind gusts.

Tilt Mechanisms
Residential umbrellas are available with integrated tilting functions which direct shade to your chosen location. Some umbrellas tilt with the push of a button and other umbrellas have this function built into the crank mechanism. Tilt umbrellas are not recommended for commercial applications

Offset Patio Umbrellas and Freestanding Patio Umbrellas
Offset umbrellas are defined as an umbrella with a cantilevered canopy which extends from a weighted slab base and vertical support out over an area to be shaded. They are considered to be a more versatile shade solution because they can be used with dining tables that don’t have holes, over a seating area or over a hot tub – really anywhere where a center pole would be an obstruction. They can be tilted and rotated, but do not move around easily because of the size and weight of the base.

The traditional patio umbrella is a freestanding umbrella that has a center pole that supports a symmetrical canopy and is anchored in an umbrella stand. The advantage of a freestanding umbrella over an offset umbrella is that it is more portable. Use a freestanding umbrella with a patio table with umbrella holes. Freestanding umbrellas should always be used with an umbrella stand for safety and security.
